2d6f291d4f Add an initial implementation of the Garmin 400 series "Aviation In" data
format.  I have a Garmin 295 to test with, but so far I haven't been able
to make this work (code should compile cleanly though.)  I don't know if
I've made a mistake in the protocol or if my 295 just doesn't support this.
More work on this to come.

32c39edf44 - make *all* class members start with underscore (not all but two)
- NEVER EVER use leading underscores for auto variables
- don't store values in auto variables for the next function call (not
  even when they start with underscore :-)   This fixed the TACAN
  channel lookup, which was supposed to be done on channel changes only,
  but was always done)
- only do frequency search if frequency has changed (this was apparently
  planned, but not finished; leftover from adf.cxx?)
- don't use double as bool switch
- some minor cleanup

e06e9ccd1e Bugfix of problem reported by Mathias Fröhlich: Ground network trace()
algorithm caused a program crash. Because there is always one waypoint more
than there are routes, the trace function should only pop_back the final route
entry at search depths of one or higher. I also added a lot of of additional
safeguarding code, due to the fact that the new trace algorithm was
apparently not as stable as I'd hoped it would be. ...

90e7c4ec43 Add a lift/drag vs. AoA graph option to the yasim tool, which
generates a data file of aerodynamic lift and drag (and L/D) against
AoA at a specified speed and altitude through a full circle.  Wrote it
to track down the YF-23 superthrust issue, but it wasn't any help.

95da644df9 Melchior sent me a property dump of the YF-23 in the wacky superthrust
state.  The only really obvious problem was a giant negative engine
RPM, which happened because of a lack of clamping in the engine code
combined with the YF-23's ability to actually reach speeds near the
engines _vMax value.  It's not clear to me that this will fix the
superthrust issue at high AoA's, but it's an obvious bug nonetheless.

16b11e311c Fixes from Maik Justus:
+ The wing compilation step was accidentally omitting regions that lie
  between the tips and the first/last control object.  That's a real
  problem for wings that contain no controls, and a significant issue
  for those that contain only a few.  I'm stunned that this went
  undetected for so long.
+ The Surface::flapLift() function was oddly returning 1.0 Newtons as
  a minimum, instead of zero.

d84043fbe2 move GL_TEXTURE_LOD_BIAS_EXT one section up and document what it does

sharper than 0, but not too sharp (and thus flickering).

010e03fab4 throw out "zoomed" tapes. These drew 60% of the scale with bullets rather
than tick marks, and looser (zoomed) than the other 40%. Rationale:

- this was only used in *one* tape of *one* HUD ("custom")
- it's not in the MIL-STD!
- doesn't seem very useful
- relies on integer scale values, while we now have float values in the new HUD

This feature would have had to be rewritten anyway. If someone needs it and
can come forward with a (MIL-)STD description, then it can be added to the
existing tape generator again (using a value->screen-position mapper function).
Otherwise it's simply declared dead.

(Yay, one TODO and a few FIXMEs less.  ;-)

8c2e595ff0 Spectacular improvement in traffic manager initialization and preparatory
work for ground based distance separation of AIAircraft.

Traffic manager initialization related changes:
- Schedules initialize "on the fly", instead of during initialization
- Invalid routes are no longer deleted, but marked as BOGUS and ignored
- Changed loading order from a distance based prioritization to a point-
  score based prioritization, resulting in a much faster establisment of
  AIAircraft near the user's plane.

Preparatory work for ground-based separation of Aircraft.
- The groundnetwork findShrortestRoute function not only returns a list
  of waypoints, but also a list of taxi "segments" (a.k.a. taxiways).
- The taxiway list is stored in the Flightplan, and updated everytime
  a new taxi leg is created.

f31088070c Fix a class of problem that could lead to needless extra time "jitter" in the flight dynamics
calculations.  We run the FDM at 120hz and compute how many loops can fit into each FG loop.
Floating point rounding could lead to a situation where we could end up running
1, 3, 1, 3, 1, 3... loops of the FDM when in fact we want to run 2, 2, 2, 2, 2...

If we artificially inflate ml above by a tiny amount to get the
closest integer, then subtract the integer from the original
slightly smaller value, we can get a negative remainder.
Logically this should never happen, and we definitely don't want
to carry a negative remainder over to the next iteration, so
never let the remainder go below zero.

0cec9290db Add a configuration property to turn on/off the use of point sprites.
Generally you want point sprites for performance reasons when enhanced runway
lighting (and smooth points) are activated.  Most hardware doesn't
accelerate the rendering of standard smooth points, so without point sprites
you will kill your night time performance if you turn on enhanced runway
lighting.

Note that enhanced runway lighting "breaks" our clever scheme to make the
runway lighting brightness vary with the relative view angle.  This means
with enhanced lighting on, all lights are equally bright no matter what
direction you view them from.  So perpendicular runways are just as bright
as runways you are directly lined up with (when enhanced runway lighthing
is activated.)

You can revert to the original lighting scheme by turning off enhance runway
lights, turning off distance-attenuation, and turning off point-sprites in
the rendering options menu.

*with* the lock, which must be dropped before calling naCall(), which

little confused.  Keep a "nasal call depth" count in the subsystem to
figure out whether we are making a sub-call and thus hold the lock.

d68723f3da Time initialization fixes. 1) Offset types "system-offset", "gmt-offset",
and "latitude-offset" should not use a precalculated value of warp.
2) Since the values of cur_time and crrGMT are identical in the current
version of the SGTime class, the calculations of the "system", "gmt", and
"latitude" are re-evaluated and updated where necessary.

98c03f95e1 Vivian Meazza:
I attach 2 new files and a diff file for the associated changes to add a
“fluxgate compass” to the instrument inventory. Whist this outputs
essentially the same data as /orientation/heading-magnetic-deg, it has to
be powered, and can be made to fail. I also followed Roy’s suggestion to
generate the error properties for this instrument here rather than in
xmlauto.xml.

When this instrument is included in cvs, I intend to use it in the Hunter,
A4F Seahawk and KC135. After a bit more research, it might be appropriate
for the Spitfire and Hurricane as well. AJ would also like to use it for his
Lightning model.

bcd9b071c5 Create a "passive" mode for the autopilot. This is analogous to running the

motions of computing the desired behavior (pitch or roll) but doesn't actually
drive the outputs.  This is potentially useful when implimenting a flight
director.

e7ed073c68 - Make two variable name modification to clarify units: altitude -> altitude_ft
and tgt_altitude -> tgt_altitude_ft.  Also fix a comment in AIBase.hxx
  indicating that the altitude is in meters, even though the usage throughout the
  code was most definitely feet.

- In AIMultiplayer.cxx, update the altitude_ft variable so that the altitude
  is reported correctly in the entity's property subtree.

- In AIMultiplayer.cxx, compute a velocity value in kts to fill in the speed
  entry in the entity's property subtree.  Note, this is not an earth centered
  reference speed, not an indicated speed and not a speed relative to the local
  airmass (that would be much harder to do.)

special lon/lat mode at all. Instead it will be regular labels that point
to these properties for displaying lon/lat.

basically the same thing), and to avoid using static buffers and all, but
... if anyone wants to make it prettier, go ahead.

4fade5839e Add a flag that allows the simulator to force "radar" computations even if

These computation include range, bearing, and angular offset relative to the

of the AI aircraft relative to the piloted aircraft without requiring a radar
system, and without requiring the AI aircraft to be within radar range.

943b7b22a7 This patch only affects aircraft (AI Models) that have no predefined
flightplan.  Such aircraft are given some initial conditions that they
fly with.  They proceed on in "freeflight" mode indefinitely.  For example,
there is a refueling demo where the tanker starts at 3000', 280 kts, and
in a 15 degree bank, and then continues to orbit indefinitely.

For these aircraft with no flightplan, I have added several control nodes in
controls/flight that allow a script or menu or external application to set
heading, altitude, bank angle, and speed.  This permits some level of interactive
or scripted control over AI aircraft.

b08a588fb1 ok, now I know why the destructor was commented out in prop_picker.cxx:
there's a bug that I had copied: update() checks each list node: if it
has no children, then a listener is attached. Later, when freeing the
children list, it assumed again that each node without children would
have a listener attached. This caused a crash when a node had children
before, but lost them in the meantime. Now we tried to remove a listener
where there never was one.

e0b1d12a60 don't abort fgfs only because a nasal script called a property function
with an invalid path, as in getprop("/sim/model/737") or x.getNode("f:1").
Forward sg's error message to the Nasal runtime error function instead, so
you get something like:

  Nasal runtime error: name must begin with alpha or '_'
    at /home/m/fgfs/Base.local/Nasal/props.nas, line 30

Unfortunately, the location points to the line where the ghost wrapper
sits, rather than the offending script line.

fdb9e94af3 ugly "fix": the constructor was commented out in prop_picker.cxx since
*many* years, so the property browser always leaked memory. I activated
this line in property_list.cxx and ... got a crash right there. So this
was the reason for it being commented out? Doing the same for now, until
I know the exact reason and can really fix it.

dfdb7f8107 the last patch fixed the AirportList ... and broke all other PUCLASS_LIST.;
Unfortunately, there's no simple way to distinguish them. plib has no
user defined widget classes, and getTypeString() -- which could be used
for that -- isn't virtual. Sigh. I'll discuss the problem on the plib list.

5a38a9d071 - undefine PUCLASS_LIST, as we have our own (old_warning--)
- PropertyObject: remove additional "values" member again
- don't create entry lists for <list>, <select>, and <combo> at dialog
  creation and delete them on dialog close, but let a separate class
  fgValueList handle this. The three widgets are now subclassed and the
  derived widget lets fgValueList manage the lists
- make <select> consistent with <list>. This breaks backwards
  compatibility, but not a single dialog in fgfs uses it and did so
  since ... forever. (Shoot me!)

Rationale: now that dialogs are a bit more dynamic than they used to be
(thanks to embedded Nasal), we have to delete and recreate entry lists
during dialog use. Deleting only at dialog closing doesn't cut it anymore.
Especially list widgets that are updated several times per second would
use up a lot of memory otherwise. The route-manager doesn't update that
often, but it did already leak. One TODO less.  :-)

Here is one patch that to make FlightGear run without floating point

nvidia driver is involved in delivering spurious floating point exceptions
to the fgfs process, causing it to core-dump occasionally without the patch.

With only this patch, FlightGear will compile and run properly on
FreeBSD 6.X as long as the nvidia accelerated driver is installed,
modulo proper switches to the SimGear and FlightGear configure script
executions.

Again, kudos to your team for the great work on the big release
push; it is super to see things come together like this!

101ca14a6d Bugfixes and feature improvements related to AI auto flightplan generation.
When AIFlightPlanCreateTaxi() function is called with the firstFlight
argument set to true, this is supposed to handle situations where the
the aircraft's timetable indicates it should have left between about 5 to
20 minutes earlier. In the previous version, all these aircraft started
taxiing from the first parking location available in the network, due
to the fact that the variable gateId was not assigned a value. In this
patch, route tracing starts from an assigned gate and the network node
following code is fast forwarded to a random location along the taxiways
to give a more realistic and natural distribution of taxiing aircraft
after startup.
    This patch further addresses some weird ballet-dancing behavior that
aircraft were showing just prior to/right after parking and which was
related to a number of more or less duplicate waypoints in the transition
from createTaxi() to createParking() to createPushBack() to createTaxi().
    Finally, a blatant typing error in the getParking() function was fixed.

f8eb3d4309 Bugfix: Non-existent AIModels could trigger a request to load scenery tiles
at (lon, lat) coordinates -1000,0. This patch fixes the AIModels/Traffic
Manager side of things. The AIModels subsystems allowed the creation of
AIAircraft with non-existent 3D models. If such a model didn't exist, the
aip class didn't get initialized, resulting in the above-mentioned bogus
position information. Here I circumvent this problem by a) only interacting
with the tile loader if the model is visible (and hence has succesfully been
initialized) and b) by disallowing the traffic manager to create AIAircraft
objects if the path to the 3D model doesn't exist.

example to set a different livery for AI models, or to set different

I am attaching a trivial patch that changes the normalization from 24 to

indicator spin value in the property tree of 0.9996 and the same value
for the pa28-161 is 1.0, so there is no harm to a 24 volt electrical
system in this change.  Should the battery or alternator put out a lower
voltage than 12 volts, the spin value goes down and the tc shows a
negative turn that increases as the voltage gets less.  This file shows
you as the author.  If you are comfortable with this change, commit it
to cvs and the tc will be correct even for 12 volt systems.

This patch makes use of the vectors now available in simgear with that past
patch. And using that it simplyfies the carrier code somehow.

- Small additional factory's to the quaternion code are done in the simgear
  part. Also more explicit unit names in the factory functions.
- The flightgear part makes use of them and simplyfies some computations
  especially in the carrier code.
- The data part fixes the coordinate frames I used for the park positions in
  the carrier to match the usual ones. I believed that I had done so, but it
  was definitly different. Also there are more parking positions avaliable now.

da6568ad50 Mathias Frhlich:
The new multiplayer patch with an extension to transmit some properties with
the base package. The properties are transmitted in a way that will not
immediately brake the packet format if we need new ones.
Even if the maxmimum number needs to be limited somehow, that format might
work well until we have an improoved packet format which is even more compact
and that does not require to retransmit redundant information with each
packet.

That part is relatively fresh and based on that what Oliver provides on his
multiplayer server web page.

The properties are transferred to the client and I have modified the seahawks
rudder animation property to use a relative property path to verify that it
works appart from the fact that you can see it changing in the property
browser.

The movement is still a bit jerky, but that can be fixed/tuned later without
again braking the packet format.

This patch makes FlightGear at least compile on MSVC. I hope I have removed
reference of my other local changes. DSP and DSW files are included for
reference. They have been reconstructed with am2dsp.pl. I had to introduce a
change to am2dsp because of the need of filenames with embedded spaces. (Yuck)

The major direction is to remove clutter like the _USE_MATH_DEFINES and have it
on the compiler command line sice there is no central include file. You will
have to put it on the command line for your locale Project files, if it not
there, already. I added the _CRT_SECURE_NO_DEPRECATE define for 2005, since it
does no harm to other VC version.

85707f1e49 The "constrained" property for a mouse mode now actually constrains
the mouse rather than wrapping it.  Wrapping around to the other side
of the screen has very bad consequences when using the mouse for
flying or viewing -- it can result in sudden jumps in the controls or
the viewpoint when the mouse jumps to another side of the screen.

Right now, the mouse is constrained to stay between 25% and 75% of the
screen on both the X and Y axis -- whenever it hits an edge, it jumps
back to the centre of the screen again (which causes no control or
view jump).

4bfd1722df Mathias Froehlich:
This patch removes some useless indirection when creating AIModels. It
obsolets AIScenario*.

AIEntities are just an intermediate copy of an other intermediate copy of an
xml file on the way from the ai scenario configuration file to the AIModels.
As such the AImodels can now be created directly from the property tree read
from the scenario file.

This reduces the amount of work needed to add an other AIModel and reduces the
amount of copy operations done during initialization.

It also moves internal knowledge of special AI models into these special AI
models class instead of spreading that into the whole AIModel subdirectory
which in turn enables to use carrier internal data structures for carrier
internal data ...

Also some unused variables are removed from the AIModel classes.
I believe that there are still more of them, but that is what I stumbled
accross ...

Tested, like the other splitouts these days in a seperate tree and using the
autopilot for some time, and in this case with a carrier start ...

5bd2ef1edb Vivian Meazza:
This patch is a combined effort by Gregor Richards, Oliver Schroeder, and
Vivian Meazza (and code cleanups and improvements by Erik Hofman). It corrects
the bug in which a Multiplayer model responds to local inputs, and the view
number bug which caused certain aircraft to appear as cockpit only models. It
passes remote properties over the net, and all major control surfaces and gear
are now animated correctly, providing that the local ~model.xml file contains
no leading "/" in the <property></property> data entries. MP objects
are now extrapolated using 1st and 2nd derivatives to make their movement
appear more smooth. The sim is now halted while a new client joins the net.

Known problems with MP are non-display of the remote client under certain
circumstances of starting/resetting, and a freeze on starting. These bugs are
long standing, and are not addressed by this patch.

Special thanks must go to AJ Macleod for his patient testing of this patch over many evenings.

We have also moved part of multiplayer into AIModels as part of the ongoing
development of MP.

6bdaa05351 Mathias Frhlich:
This patch limits the maximum simtime we do simulation computations for.
That is highly sensible if you run flightgear in valgrind or some realy slow
debug build. In such a case it is possible that flightgear gets totally
unresponsible, because simulation time might increase slower than real time.
That patch introduces a maximum simulation time per rendered frame to limit
that effect.

If the property /sim/max-simtime-per-frame is set to something strictly
positive, the simulation time is limited to that value.
The default is unchanged - no limit.

Anyway, from the point of view of gui responsiveness and responsiveness to
realtime controls like joystick inputs it might be a good idea to limit that
by default to say 1 second. If you have less than 1fps, flightgear is
unplayable anyway and I believe we do not longer need to care for realtime
correctness for that case ...

96c0a7bbc1 add _setlistener() function, so that slow property polling loops can be
replaced with efficient listener callbacks. One use is the new FPS display.
This is reviewed and OK'ed by Andy, relatively trivial and separated from
the rest of Nasal, so problems are quite unlikely and confined to users of
this function.

The callback is executed whenever the property is written to -- even if
the value didn't change. The triggering Node is available via cmdarg().

Examples:  _setlistener("/sim/crashed", func {print("haha!")});
           _setlistener("/foo/bar", func { print(cmdarg().getPath() ~ " changed")})

This can be useful for adding entries from other config files (aircraft
specific or local). I'd say aircraft files can use indices starting with
[100] and local files starting with [1000]. Such high number will never
collide with an entry in menubar.xml, even if entries are added/removed

Unfortunately, we don't have an easy way to access the puObjects
only by knowing the respective XML property node, because the
menu structure was built by plib from string lists. That's why
we walk the puMenuBar tree and store {property node}->{puObject*}
pairs in a map. With this infrastructure in place we can now
easily enable/disable entries, but we can also make other changes
to menu buttons as we see need. The structure of puMenuBar is
described in the pui documentation, so it's less of a hack than

e807c7f95c A long, long time ago, a bug was inadvertently introduced into the threaded
metar fetcher.  Effectively this caused the metar thread and the main
thread to both attempt to fetch weather data.  This could lead to long pauses
when the main thread decided to fetch the weather, and introduced a race
condition that could cause a segfault/crash.

Investigating this issue, I discovered that even longer ago, someone confused
#defines and #ifdef symbols with C/C++ variables.  If I #define XYZ 0 it is
defined so #ifdef XYZ is true, not false like a variable.  Our thread
detection made this mistake and there were follow up patches to work around
it.

So I fixed the configure script (ahhh, reading the autoconf manual is highly
recommended excercise for people editing the configure.ac file.)  I also
discovered that we were hardwiring with_threads=yes with no way via configure
options to disable threads from the build so I fixed that.

Then I patched up the #ifdef's scattered through the code to match the
configure script changes, oh and by the way, I stumbled upon a past typo
that led to the race condition in the metar fetching thread and fixed that.

0eef853caa This is an ugly fix for an ugly problem. And no, the two uglies don't cancel
each other out. The problem is this: if we press, for example, "Ctrl-a", but
release the "Ctrl" modifier button *before* the "a" button (which nobody does
intentionally, but which happens all the time), then we don't get the RELEASE
signal on "Ctrl-a" (keycode 1), but on the "a" (79). But "a" hasn't been
pressed, so the signal is dropped. And who releases "Ctrl-a"? Nobody!
So the next PRESSED signal for "Ctrl-a" is ignored, too. It is still
"pressed" after all, isn't it? That's the reason for the occasional
non-functioning of keys.

Due to the nearing 0.9.9 release, I only commit a crude last-minute fix.
It's not as intrusive as it looks, and shouldn't be "dangerous" at all.
It only makes sure that when we get an unexpected RELEASE for one letter
key ("a") that the two twins "A" and "Ctrl-A" are released if they are
still in "pressed" state.

The proper fix will be to let fg_os{,_sdl}.cxx always report presses on the
same key ("a", "Shift-a", "Ctrl-a", "Alt-a", and other combinations of
modifiers) as the *same* key (97), only with modifiers appropriately set.

14c3bc5932 Architectural fix allowing the "tip" popups (FOV, view name, etc...)
to pop themselves down while the simulator is paused.

The problem was with the "real time" queue in the event manager,
causing the third argument of Nasal's settimer() (a flag for "sim
time") to be ignored.  Inverts the default sense of the argument, as
there are lots of uses of settimer() in the current code, almost none
of which want to use real time.

Note this fix introduces a header file incompatibility in SimGear --
be sure to update.

029dda3297 In the process of changing, adding and removing files the last few years
there was the situation where four directories contained jst two files,
of which three directories were aircraft related, and one directory contained
test code from Curt that might be better of in SimGear anyhow.

This is just a patch to move a bunch of files to new locations. In case of
local changes to any of them you can do the following:

move replay.[ch]xx from src/Replay to src/Aircraft
move control.[ch]xx from src/Control to src/Aircraft
move ssgEntityArray.[ch]xx from src/Objects to simgear/screen

In addition it has been decided only to use .[ch]xx files in all directories
unless it's contained within an FDM specific directory, in which case the
author is free to do whatever (s)he wants.

In this repspect the following files have been renamed in src/Multiplayer:

tiny_xdr.[ch]pp has become tiny_xdr.[ch]xx
multiplaymgr.[ch]pp has become multiplaymgr.[ch]xx

58179758af add support for a <hide> property, which hides whole XML groups (widgets
or data blocks) from layouter and dialog creator. This is required for
dynamically generated/modified dialogs. Parts in the XML file can be
hidden and turned on by the C++ code. Other hidden parts can be used
as templates that are multiply used. Hidden datablocks can contain
strings that are used in dialog context, that are easier to translate
or modify in the XML file.

76f4bc1cef Piston engine oil temperature model from David Luff:
Attached is a patch to add oil temperature to the YASim piston engine
model.  This brings to life one of the pa28-161's otherwise 'dead'
guages.  It's a pretty simple 'model' based on temperatures and warmup
times I've observed in the labs on auto engines and run through my
dodgy-memory filter.  It does the job of populating the guage with
something plausible though.

I had a quick view over the ssgBase::ref() calls in flightgear.
I made them all symmetric and used ssgDeRefDelete to dereference them.
This has the basic advantage that ssgDeRefDelete additionaly deletes the
memory instead of just decrementing the reference cound without deletion ...

This includes an incorrect deref instead of a ssgDeRefDelete in the placement
transform registration I introduced earlier. I believe that this causes the
problems with long flights (unverified, but with a big propability).

occure when you start on the carrier not does it occure with JSBSim and my
really often used testaircraft. So I really need to improove my helicopter
flying qualities.

I was under the impression that *all* FDM's call

FGInterface::updateGeo*Position(..)

so set the new position in the FDM interface. Therefore I had added at the
some code that updates the scenery elevation below the aircraft to *those*
functions.
Ok, not all FDM's do so :/

The attached patch factors out a function computing the scenery altitude at
the current FDM's position. This function is also used in those FDM's which
need to update this value themselves.
Also this patch restores the nearplane setting and uses the current views
altitude instead of the current aircrafts. I think that this should further
be changed to the eypoint's agl in the future.
The agl is again ok in YASim's hud.

0bb1494452 David Luff:
Attached is a patch to the airport data storage that I would like committed
after review if acceptable.  Currently the storage of airports mapped by ID
is by locally created objects - about 12 Meg or so created on the stack if
I am not mistaken.  I've changed this to creating the airports on the heap,
and storing pointers to them - see FGAirportList.add(...) in
src/Airports/simple.cxx.  I believe that this is probably better practice,
and it's certainly cured some strange problems I was seeing when accessing
the airport data with some gps unit code.  Changes resulting from this have
cascaded through a few files which access the data - 11 files are modified
in all.  Melchior and Durk - you might want to test this and shout if there
are problems since the metar and traffic code are probably the biggest
users of the airport data.  I've also added a fuzzy search function that
returns the next matching airport code in ASCII sequence in order to
support gps units that have autocompletion of partially entered codes.

More generally, the simple airport class seems to have grown a lot with the
fairly recent addition of the parking, runway preference and schedule time
code.  It is no longer just an encapsulation of the global airport data
file, and has grown to 552 bytes in size when unpopulated (about 1/2 a K!).
 My personal opinion is that we should look to just store the basic data in
apt.dat for all global airports in a simple airport class, plus globally
needed data (metar available?), and then have the traffic, AI and ATC
subsystems create more advanced airports for themselves as needed in the
area of interest.  Once a significant number of airports worldwide have
ground networks and parking defined, it will be impractical and unnecessary
to store them all in memory.  That's just a thought for the future though.

It will not work on system not using configure in the build process (excluding

the computer carries out other tasks - changing window size is a known
example. This bug is outwith this code.

I have prepared a patch that:
- Introduces a FGTileMgr::scenery_available method which asks the tilemanager
  if scenery for a given range around a lat/lon pair is already loaded and make
  use of that method at some -9999 meter checks.
- Introduces a FGScenery::get_elevation_m method which queries the altitude at
  a given position. In constrast to the groundcache functions this is the best
  choice if you ask for one *single* altitude value. Make use of that thing in
  AI/ATC classes and for the current views ground level. At the current views
  part the groundcache is reused if possible.
- The computation of the 'current groundlevel' is no longer done on the
  tilemanagers update since the required functions are now better seperated.

Alltogether it eliminates somehow redundant terrain level computations which
are now superseeded by that more finegrained functions and the existence of
the groundcache. Additionally it introduces an api to commonly required
functions which was very complex to do prevously.

83b414482f Harald JOHNSEN:
I did some profiling of the code and found a few interessant things. Some corrections are obvious like the one in the multiplayer code, the fps is no more divided by 2 or 3 when another plane is on screen.

Other things like collision detection and computation of agl can not really be optimized. I changed a few things in hitlist.cxx but this only give a very low increase of fps. The groundcache eats a lot of cpu but I think that the real way to do it is to use a real collision system like OPCODE or something like that.



And I added an option to disable the recording of replay data. It takes more cpu than we can think.


Changes
=======

- panel.cxx :
  moved the computation of the instruments diffuse color outside the texturelayer code
  since this is constant during a frame, this is a big speedup for 2D panels ;

- hitlist.cxx :
  changed the computation of the intersection between ray and triangle, optimized
  the sphere culling by using a normalized direction vector. This can give a
  35% speedup on the computation of elevation in some situations ;

- renderer.cxx, acmodel.cxx :
  call ssgDrawAndCull with plane scene graph in external or internal view,
  calling ssgDrawAndCull with the root scene graph was drawing other players plane
  a second time in multiplayer mode ;

- mplayer.cxx :
  removed the calls to ssgFlatten and ssgStripify because it was degenerating models,
  causing a massive drop in frame rate ;

- replay.cxx :
  added an option to disable the recording of the flight

- fgclouds.cxx :
  changed the path of cloudlayer properties to match preferences.xml ;
  set the altitude of clouds from scenarios to a more correct value if metar is not enabled ;

  - changed again the cleanup code for objects inside a tile because it could crash on rare occasion ;
  - the culling of shadow casters has been rewritten to traverse the scene graph, it should be
    a bit faster when there is a lot of objects ;
  - the range selector was not correctly handled, sometimes the wrong LOD was casting shadows.
  - added the option to display aircraft's transparent objects after the shadows, this will
    reduce the problem of shadows being hidden by the transparent object (propeller disk,
    rotor, etc). A side effect is that aircraft's transparent objects won't receive shadows
    anymore. This is usually a good thing except when the aircraft use a 'transparent'
    texture where it should not. A transparent texture in the plib context is a texture
    with an alpha channel or a material with alpha <= 0.99.

- model.cxx, animation.cxx, shadowvolume.cxx :

- tower.cxx
  - correct a rare bug where all occurences of the aircraft are not deleted from the

Preliminary support for a fontcache is added which prevents fonts from
being loaded more than once and takes care of freeing them up again.
The fontcache isn't used yet since there seems to be a problem somewhere.

4df7a3e9f8 Mathias Frhlich:
I have introduced the posibility to start directly on the carrier.

With that patch you will have a --carrrier=id argument where id can either be
the pennant number configured in the nimitz scenario or the carriers name
also configured in the carriers scenario.
Additionaly you can use --parkpos=id to select different positions on the
carrier. They are also configured in the scenario file.

That includes the switch of the whole FGInterface class to make use of the
groundcache.
That means that an aircraft no longer uses the current elevation value from
the scenery class. It rather has its own local cache of the aircrafts
environment which is setup in the common_init method of FGInterface and
updated either manually by calling
 FGInterface::get_groundlevel_m(lat, lon, alt_m);
or implicitly by calling the above method in the
 FGInterface::_updateGeo*Position(lat, lon, alt);
methods.
A call get_groundlevel_m rebuilds the groundcache if the request is outside
the range of the cache.

Note that for the real usage of the groundcache including the correct
information about the movement of objects and the velocity information, you
still need to set up the groundcache in the usual way like YASim and JSBSim
currently does.
If you use the native interface, you will get only static objects correctly.
But for FDM's only using one single ground level for a whole step this is IMO
sufficient.

The AIManager gets a way to return the location of a object which is placed
wrt an AI Object. At the moment it only honours AICarriers for that.
That method is a static one, which loads the scenario file for that reason and
throws it away afterwards. This looked like the aprioriate way, because the
AIManager is initialized much later in flightgears bootstrap, and I did not
find an easy way to reorder that for my needs. Since this additional load is
very small and does only happen if such a relative location is required, I
think that this is ok.

Note that moving on the carrier will only work correctly for JSBSim and YASim,
but you should now be able to start and move on every not itself moving
object with any FDM.

486b59a431 TJ:
Annexed an IVSI (instantaneous ertical speed indicator), which bypasses a
limitation with Concorde :

- the cruise at Mach 2 must be with a slow climb rate of 50/60 ft/min
  (2h from 50000 ft).
- with /velocities/vertical-speed-fpm, the real climb rate (altimeter) varies :
  One must constantly (every 5-10 minutes) change the vertical speed hold of
  the autopilot between 10 ft/min and 200 ft/min.
  This is very annoying because not a constant offset : that could be a lack of
  sensitivity of /velocities/vertical-speed-fpm (FDM ?).

This new IVSI :
- Is an emulation with works with environment pressure : a real IVSI works with
  static pressure (with lag) + accelerometers.
  It is not forbidden to later upgrade to the real model.
- Doesn't require a tuning of the autopilot made with
  /velocities/vertical-speed-fpm (also tested with 737, 747) :
    Concorde's autoland works without update.

8027023862 - fix bug that let <mod-up> bindings be executed before the nasal init
block (this required to move most of init() into postinit())
- undo the "which" pseudo-namespace workaround, and do it proper:
- let all nasal code in a joystick config file be executed in its own
  namespace. This allows to define functions in the init block that
  can be used throughout the driver file, and to write state variables
  in one binding, while reading them in other bindings, all without
  having to make sure that the values aren't lost in between, or collide
  with another joystick driver's code.
      For this the input subsystem creates a namespace for each joystick:
  "__js0" for joystick 0, etc. The two leading underscores are there to
  avoid collisions with user defined modules (similar to internal compiler
  variables). The namespace shouldn't be used explicitly, at least not in
  releases, and not from outside code, except for testing purposes, for
  which it can be useful. (If using the Cyborg joystick as js[0], you
  can read the modifier level as "__js0.modifier" from any nasal context.)

6dd82d0502 Updated electrical system.
These changes represent some attempts to bandaid and patch a hopelessly
flawed system to impliment basic battery charging/discharging as well as
provide the ability to model ammeter gauges and draw current from multiple
sources (like load balancing multiple alternators in a multi-engine aircraft.)
The system design forces all these things to be horrible hacks or depend
on extremely subtle system side effects and call ordering so they may or9
may not work to one degree or another.

As mentioned in the mailing list, my recommendation is to move away from
using this system and instead build a procedural electrical system using
nasal.  Sometime in the future we hopefully can impliment a better conceived
data driven electrical system model.

I made YASim query the the ground cache at the wrong place. This one fixed
this, one can now land the bo105 on top of the oracle buildings  :)

3.
Is a followup of the scenery center update code: Register the scenery center
transform at the time it is put into the scene graph not at creation time.

4.
I held that part back from the past hitlist patch, because I hoped that it
will be sufficient (and the last one was in fact the biggest part) without.
As some test cases from Melchior showed me, it is not. We have additionally
to the wrong computed transform from the prevous patch some roundoff
problems. This patch adds some small tolerance to for the point in triangle
test.
... may be one even needs to increase the eps value further if starting at
some tile boundaries still fails.

5.
That is a big chunk.
Tested now for two days while hunting the second patch  :) .
That is a partial rewrite of the groundcache to use its own datastructures for
that flat scenegraph in the cache. The basic advantage is, what Erik
suggested, to precompute some often used values of these triangles. Also
allmost all computations are now in double precision which should decrease
(hopefully fix), together with a similar tolerance for some point in triangle
tests, the problems with 'no ground below aircraft'.
I am playing with octrees for the groundcache, that will finally solve the
performance problem when high triangular count models end up in the
groundcache. This patch is also some prework for those octrees ...

1)  The AIStorm sets the properties:
         /environment/turbulence/magnitude-norm
         /environment/turbulence/rate-hz

    The actual turbulence effects are handled by the FDM.
    If the effects are deemed unrealistic, then that will
    have to be fixed in the FDM(s).


2)  The zone of turbulence is cylindrical, and is centered
    at the AIStorm's lat/lon.  The diameter is set with
    <diameter-ft>, the top with <height-msl>, the bottom is
    assumed to be at <altitude> minus 1000 feet.

3)  Note that the zone of turbulence may not match well with
    the visual model of the storm.  In this case I had to
    x-offset the storm model by 4700 meters to match the zone
    of turbulence. (i.e. the storm model is 4700m off center).

4)  While I was in there I also increased the speed of the
    lightning flashes to look more realistic.

  when the metar property says so)
- added a lightning effect (enabled in the rendering dialog) : cb clouds spawn
  new lightnings
- added a dialog to select from different weather source : metar/property,
  a 'fair weather' environment and a 'thunderstorm' environment.

4c10ef139c Mathias:
I have done a patch to eliminate the jitter of 3D-objects near the viewpoint
(for example 3D cockpit objects).
The problem is the roundoff accuracy of the float values used in the
scenegraph together with the transforms of the eyepoint relative to the
scenery center.

The solution will be to move the scenery center near the view point.
This way floats relative accuracy is enough to show a stable picture.

To get that right I have introduced a transform node for the scenegraph which
is responsible for that shift and uses double values as long as possible.
The scenery subsystem now has a list of all those transforms required to place
objects in the world and will tell all those transforms that the scenery
center has changed when the set_scenery_center() of the scenery subsystem is
called.
The problem was not solvable by SGModelPlacement and SGLocation, since not all
objects, especially the scenery, are placed using these classes.

The first approach was to have the scenery center exactly at the eyepoint.
This works well for the cockpit.
But then the ground jitters a bit below the aircraft. With our default views
you can't see that, but that F-18 has a camera view below the left engine
intake with the nose gear and the ground in its field of view, here I could
see that.
Having the scenery center constant will still have this roundoff problems, but
like it is now too, the roundoff error here is exactly the same in each
frame, so you will not notice any jitter.

The real solution is now to keep the scenery center constant as long as it is
in a ball of 30m radius around the view point. If the scenery center is
outside this ball, just put it at the view point.

As a sideeffect of now beeing able to switch the scenery center in the whole
scenegraph with one function call, I was able to remove a one half of a
problem when switching views, where the scenery center was far off for one or
two frames past switching from one view to the next. Also included is a fix
to the other half of this problem, where the view position was not yet copied
into a view when it is switched (at least under glut). This was responsible
for the 'Error: ...' messages of the cloud subsystem when views were
switched.

- corrected some strange behavior when playing with the render dialog options
- the density slider is now working : if you are fps limited and still want to see clouds in
  the distance you should play with that
- added the choice for texture resolution, its more comprehensible now (before it was
  wrongly allways choosing 64x64 textures)
- changed the initial texture size : you now have 64 texture of 64x64, this uses 1Mo of
  texture memory (before it was 20 texture of  256x256, that took more memory and there was
  not enought impostors)
- sun vector is now right so the lighting is a bit better
- removed useless sort and light computations for impostors, this should save a lot of cpu
- blending of distant cloud is more accurate now
- clouds are now positioned correctly, they don't try to escape you anymore
- no more red/white boxes around cloud

3)  AIManager::328  ,  I changed the fetching of the user state to occur every

by node pointer.  It should be faster now, and more accurate too.  This helps

86249209b9 This is a work in progress. I am extending the "ExternalPipe" protocol to
have a "property" mode as well as the original "binary" mode.  The property mode
will allow the remote module to request any set of properties, and it will send
those properties each frame.  The remote module can reply with a list of arbitrary
property name/value pairs to update on the FlightGear side.

This is a first stab, so it's not the cleanest, most well concieved code, but it
allows an external module (communicating via a pipe) to have a huge amount of
flexibility in the data in can access and update.

showDialog() is careful not to create a new FGDialog() if a dialog with the
same name is already open (active). But at this point it is already too late:
newDialog(), which was called shortly before, has already overwritten the
dialog properties. This leads to animated garbage in the best case, and a
segfault in format_callback() in the worst case.

- GUI::newDialog(): Don't you overwrite properties of an active dialog!
- GUI::readDir(): You may do that, but delete the old dialog first!
  (necessary for reloading the GUI)

- FGDialog::makeObject(): only set format_callback() with setRenderCallback()
  if the property is "live". Otherwise, only call it once at construction
  time. This isn't only a performance improvement. Without this the label
  was growing until it hit the limit (256).

The dialog handling has been written at a time when only one dialog was

- check full object tree on button press, not only the outmost layer;
  and don't give up just because we are in *something* (which could well be
  something harmless, like a group); only ignore a few, sensible objects
  (we don't want to drag after a click on a button or into an input field)

- don't lose dialogs as easily when dragging too fast (it does still happen
  if one manages to enter an editable field while dragging, but this is
  a plib problem and I don't feel like fixing that now  :-)

I have done some cleanup where I moved some values out of classes where they
do not belong and such stuff.
Also the fols offsets are now named in the carrier xml file with a more
verbose name (flols-pos/offset-*) than before (only offset-*).
There is a little preparation for definitions of parking positions on the
carrier which should later be used for starting flightgear directly on the
carrier.

I implemented the method pointed out by Norman. It works great on windows and saves me a lot of CPU cycles. This way, I can get the same framerate in moderately populated areas and have CPU idle 50% of the time instead of wildly looping in the NVidia driver while waiting to sync on vblank.

It has been tested on Linux by Melchior. He saw the same gain in CPU cycles.

40170cb722 The view frustum is defined in plib apps using calls to ssgSetFOV() and
ssgSetNearFar().  This by default creates a symmetric view frustum which is
typically what an application wants.

However, to get control of the view frustum in order to build support for
asymmetric view frustums, we need to wrap these calls with a bit of our own
logic.

This set of changes wraps all calls to ssgSetFOV() and ssgSetNearFar() with
FGRenderer methods.

I also standardized how the FGRenderer class is handled in globals.[ch]xx.
This led to some cascading changes in a variety of source files.

As I was working my way through the changes, I fixed a few warnings along
the way.

Ability to set desired sampling interval in seconds. Use <Ts> under <config>

     <beta>1.0</beta>    <!-- input value weighing factor -->
     ...
     ...
</config>

Ts defaults to 0.0, so if you don't set it it samples at the highest possible
frequency.


Add an offset to the input variables (input and reference).
Example:
    <reference>
      <prop>/controls/flight/elevator</prop>
      <scale>-1.5</scale>
      <offset>1.0</offset>

Attached is a patched runways.cxx.  This fixes the find runway nearest to a given heading code.  This was returning the last runway loaded at a given airport, not the nearest runway to the heading requested (which seems to always be 270deg by default).  I have no idea how this has survived unnoticed for so long - I think it might be because you need to start at an airport with a runway near to 27 and one much greater than 27 eg. 36 to really tickle it, otherwise the runway nearest to 27 tends to be the final one loaded anyway.  Try starting at KARR with and without the patch and note the surface wind.  This should go in before the release.

I've finished the emigration of the radiostack, and I've also removed it
completely. It turned out that the comm radio is completely implemented in
the ATC subsystem. I've changed the affected ATC files to point
to /instrumentation/com, but I guess that the maintainer of the ATC code
should decide wether to make it configureable, and how.

I also had to change some files in Network and Main. The changes in network
should be obvious, but the changes in Main were a bit suspect. The files
included radiostack.hxx, but they weren't directly depending on
radiostack-hxx. They were depending on other files that were included by
radiostack.hxx. I got it to compile, but I'm not sure if I included the
correct directly depending file.

For the data directory I changed every occurrence of /radios/
with /instrumentation/ with this simple one-liner that I found on the net:

find -name '*.xml' -type f | xargs perl -pi -e
's/\/radios\//\/instrumentation\//g'

Instead of me sending all the files that got changed by this I suggest that
you execute the one-liner yourself. Of course I can not guarantee that this
will work perfectly, but I considered hand editing to be not an option (I'm
lazy). I don't want to test every aircraft to see if everything still works,

the pilot's eye above/below the 3.5 deg glide slope. The apparent position
of the source light relative to the fixed green datum lights allow the pilot
to 'fly the meatball'. The green 'cut' lights flash when the pilot's eye is
below the coverage of the lowest (red) source light.

TODO - add rules for the operation of the wave-off lights.

I understand that the new hud/runway feature is still very experimental,
and that the search criteria for the active runway don't necessarily make
much sense. (We are searching for a runway on /sim/presets/airport-id
that matches the current wind direction best, and not the tuned in ILS
runway or something!)

Anyway: the new hud code completely denies the possibility of
globals->get_runways()->search() not finding a runway and returning false.
There's always a runway found at KSFO, but not so at e.g. LOXL, in which
case we are handing garbage over to sg_geodesy.cxx and find ourselves
caught in an endless loop in geo_direct_wgs_84().

Attached are the two files and the patch to integrate that cache into
FGInterface.

The code is nowhere used at the moment, the fdm's need to be updated to use
that ground cache. The JSBSim-dropin.tar.gz from Martins ftp server does this
for example.

The carrier's scenegraph is not yet processed to be visible for ground
intersection testing. So the only benefit up to now is that the api is set
up. Using this I can put the changes to make JSBSim work with that into
JSBSim's cvs. Also I aim to provide Andy a patch to make use of that with

62df58d4f8 I have added Aaron Wilson's virtual 3d runway projection to the HUD.
Aaron says:

I just got the virtual runway hud projection working on all views and
2D & 3D HUDs.  It is working awesome(see below).  I have attached every
file that was modified (hud.hxx, hud.cxx, and the default.xml for the hud)
and every file that was added (hud_rwy.cxx and runwayinstr.xml).

Just a quick overview of how the instrument works.

The virtual runway is projected by getting the "cockpit view" of the
runway in 3D and projecting the points on to the 2D HUD.  Therefore, the
virtual runway will be displayed the same in every view.  For example,
you can land an aircraft from the "Tower View" by flying the HUD.  Also
if you're in "Cockpit View" and it is centered then the virtual runway
lines will perfectly outline the actual runway.  I am getting the active
runway via the wind like done in the ATC classes, which may need changed.
Also, I made the assumption the view 0, in view manager, is always the
cockpit view, which may need changed as well.

The runway configuration file will allow you to specify a center offset
(x,y) and a bounding box (width,height).  You can also configure the line
stipple pattern for the outside and the center line.  For instance, if
you wanted a 0xFAFA pattern, then specify 64250 as the value.  If you
want a solid line, you can specify -1 or 65535 (0xFFFF) and zero will
turn the line off.  It also draws a runway indication arrow when the
runway is not in the HUD or it can be drawn all the time if arrow_always
is true.  The arrow will point in the direction of the runway (2D) by
rotating around the center  at a radius of arrow_radius.  If you wish to
turn the arrow off, you must set the arrow_scale <=0.  The arrow really
should be 3D arrow that points to the runway (or points in the direction
of the aircraft-to-runway vector).

The moving ai models will jump around realtive to the moving aircraft model.
I can see that with the carrier but others have noticed that too with ai
aircraft before.
The reason is that all SGSystems are called with a dt value which is not
necessarily a multiple of 1/hz.
In contrast, most FDM's use the _calc_multiloop function from FGInterface
which forces the time update to be a multiple of 1/hz for the FDM aircraft.
As a result, in the worst case, the FDM aircraft has moved nearly 1/hz seconds
further than the rest of flightgear (1/120sec*300kts that is about 1.3m).
That patch forces the time update to be a multiple of 1/hz.

I attach the latest version  of Nimitz. The textures have been improved. A glide-path has been added, it is on by default, but can be switched off by means of the properties browser: /ai/models/ship/controls/glide-path. The origin has been adjusted to the turning pivot and approximate roll center.

Modified AiShip files are also attached. These allow the radius of the turning circle of a ship to be input. The turning circle is adjusted for speed and rudder angle. Roll has been corrected so that a ship leans out of a turn, not inwards like an aircraft. The roll angle is adjusted for speed and rudder angle (yes, application of more rudder reduces roll angle - rudders act as stabilizers).

Here's some code that defines a top to thermals.  When the top of a thermal is
reached the strength is phased-out linearly over the next 100 feet of
altitude.  At first I tried just capping the thermal at the top, but the
change in thermal strength was too fast for the FDM to handle well.

Included is a new version of the thermal scenario that includes a top
(height-msl) to the thermal.  The default value is 5000 feet.

2. Double exponential - Two exponential filters in series. This filter has a
   "steeper" frequency response curve. It filters "better" than the single
   exponential.

3. Moving average - Averages a number of inputs.

4. Noise spike - limits the amount that the output value can change from one
   sample to the next.

Filters 1 and 2 are characterised by it's filter-time in seconds. For filter 3
you have to set the number of input samples to average over. For filter 4 you
set the maximum allowed rate of change as [1/s]. Since the sampling interval
(dt) isn't constant we have to calculate the maximum allowed change for every
update.

Example of a double exponential filter with filter time 0.1 seconds, that is
1/0.1 = 10 Hz.

  <filter>
    <name>pressure-rate-filter</name>
    <debug>true</debug>
    <type>double-exponential</type>
    <input>/autopilot/internal/pressure-rate</input>
    <output>/autopilot/internal/filtered-pressure-rate</output>
    <filter-time>0.1</filter-time>
  </filter>

This would go in the autopilot configuration file.

I've also removed the filtering of the "pressure-rate" helper value, use the
new filters if you want to filter it!  ;-)

As I had reported on 2004/8/4 00:02:56 ("yasim + bo105 + vrp + @#%$#@ == argh!")
there must be a bug somewhere in YASim, which is responsible for the Bo105
turning around the FDM origin (nose tip) rather than the CG. Some people assumed
that I was just another victim of the "view offset" illusion, but this wasn't
and isn't the case.

Maik Justus (the rotor man) has now supposedly found the bug in YASim[1].

41e217fb9a Continued work to clean up the hires screen shot code and move it back towards
a working state.  I still see an anomoly when taking a screen shot from inside
a 3d cockpit, but external (chase/tower) views seem to work well.  I also
added a property to control how many screen-res tiles are generated in the
output.  Theoretically, you can now generate unlimited resolution screen shots,
or limited only by your disk space and patience.

Today I successfully generated a 20*1024 x 20*768 (20480x15360) resolution
screen shot.  If you rendered that at 100 dpi it would cover a poster of
about 17 feet by 12.8 feet.

Good luck trying to display something that big or convert it to anything
useful on a typical PC. :-)

should be the sub-sonic value, so bullets will need changing.

328053fe23 Vivian Meazza:
The calculation of submodel mass from weight has been moved from AIBallistic
to Submodel so that it is calculated only once, rather than on every
iteration as a present. The parameter <contents> has been added, primarily
so that droptanks will have the proper mass. It is the path to an
appropriate property containing a weight in lbs.

Care has to be taken with the use of <contents> because after a reset there
appears to be a delay in submodel instantiation (dt not properly reset???)
and the weight property is not always picked up before it is set to zero in
the key bindings. Slightly hard to explain. It works fine if FGFS has not
been reset though. There is a partial solution which involves the rejigging
of the fuel and gui nasal scripts, but there is still the visible delay in
instantiation to be resolved. I've nearly done the nasal fixes, which will
form part of an update to the Hunter only. I'll probably complete those
later today.

986492d72d Finish what was committed in a broken state yesterday.
Split up main.cxx into a program manegement part (which remains in
main.cxx) and a render part (the new renderer.?xx files). Also turn
the renderer into a small class of it's own. At this time not really
exctining because most of the stuff is still global, but it allows us
to slowly migrate some of the global definitions into the new class.

The FGRenderer class is now managed by globals, so to get the renderer
just call gloabals->get_renderer()

At some pijt it might be a good idea to also turn the remaining code in
main into a class of it's own. With a bit of luck we end up with a more
robust, and better maintainable code.

I had to reverse a number of signs to get it right. I took the opportunity
to add roll to the submodel so that droptanks will come off with the right
orientation. I have neither added the rotational speed to the submodel, nor
yaw, so if you release droptanks with  significant roll rate or yaw angle on
the aircraft the submodel will not be quite right. Straight and level, or
nearly so, is fine.

cc3d0221ea Make a subtle change to tile loading/unloading policy in order to make the tile
paging system much more robust when position change is very rapid and sporadic.

Recall that we must load 3d models in the main render thread because model
loading can trigger opengl calls (i.e. with texture loading) and all opengl
calls *must* happen in the main render thread.

To accomplish this we load the base tile in the pager thread and build a work
queue of external models that need to be loaded.  We never allow a tile to be
paged out of the tile cache until all it's pending model loads are complete.

However, when changing position very rapidly, we can quickly create a huge
backlog of pending model loads because we are changing positions faster than we
can load the associated models for the existing tiles.  The end result is
that tiles that are long out of range can't be removed because there is still
a huge backlog of pending model load requests and memory blows up.

This change being committed allows the tile paging system to remove tiles
if they are out of range, even when there are pending models to load.  The
model loading code in the render thread can now check to see if the tile
exists and discard any model load request for tiles that no longer exist.

This situation should never occur in normal operation, but could occur in
"contrived" situations where an external script was rapidly changing
the simulator position to then be able to query FG terrain height, and doing
this for a large number of points that are distributed across a large area.

The maths, so far, is now correct. Roll and pitch are now both in the
correct sense. The aircraft velocity is added correctly to the
submodel velocity, and the submodel is now visible when instantiated.

However, the velocity is measured at the aircraft centre. To be totally
correct we ought to take into account the aircraft's rotational
velocity. We have pitch rate and roll rate available, but not yaw rate
(small anyway).
