464f036f35 Here is a cleaned up hitlist that should solve the PLib conflict
and fixes a 'potential bug' if the FGFS View code were to change

I also consolidated the specialized IntersectLeaf()
as they really didn't gain us much outside of their having
'more direct access into the SSG controlled data'

I would like to see the fgCurrentElevation functions moved
out of hitlist.cxx.

The one obstacle is their being dependent on my PLib
auxillary functions

ssgGetEntityTransform()
ssgGetCurrentBSphere()

code has been run through astyle with the default options

d0eaafb1e1 Patches from Tony Peden to separate property XML I/O operations into a
separate header file.  This change will help integrate properties into
JSBSim.

Also, I (David Megginson) removed most of the SimGear include
statements from globals.hxx, reducing the amount of recompilation
every time SimGear changes.  This required making minor changes to a
lot of files that were depending on the side-effects of the inclusions
in globals.hxx.

2e4f836a98 General cleanups to cut cross-dependencies and speed up compilation.
Added two new properties:

  /environment/temperature-sea-level-degc
  /environment/pressure-sea-level-inhg

These are now supported in FGEnvironment as well, though they always
have the same value for now.  They need to be hooked up to the FDMs.

eaf9fa7621 Added FGEnvironmentMgr to provide information on the environment in
different locations, and hitched it into FGGlobals.  FGEnvironmentMgr
has taken over as the subsystem, while FGEnvironment is simple the
information that it returns.  I've removed current_environment
completely -- everything now uses properties or goes through
FGGlobals.  FGGlobals itself has a couple of useful methods:

  const FGEnvironment * get_environment ();
  const FGEnvironment * get_environment (double lat, double lon, double alt);

The first one returns the environment data for the plane's current
position, while the second returns the environment data for any
arbitrary location.  Currently, they both return the same information,
but that will change soon.

dea7284cc7 Restructured the 'freeze' property a bit. We now have

/sim/freeze/master is bound to the 'p' key via keyboard.xml, however,
/sim/freeze/fuel is not bound to anything at the moment so you must
change it via the external property interface, or specify an initial
value on the command line.

1fa4c88d0e Updates to build system to better support automake-1.5
- automake-1.4 sets default values for INCLUDES which we can't
  overwrite.
- automake-1.5 renames this to DEFAULT_INCLUDES and leaves INCLUDES
  open for the developer to use.

Thus for automake-1.4 we are forced to 'append' to INCLUDES and in
automake-1.5 we can just set the value to whatever we like.
Unfortunately, the behaviors of the two versions are mutually
incompatible.

The solution I am committing now works for both versions but
automake-1.5 generates a lot of spurious warning messages that are
annoying, but not fatal.

36de63366b I just nailed an especially annoying tile cache scheduling bug.
What was happening was that we screwed up and scheduled tiles for
(lon,lon) rather than (lon,lat) ... note the typo.  This generated
bogus tile id's which the system happily accepted, put into the tile
cache system, and attempted to load.  The problem was that these bogus
tile id's were negative where as all valid tile id's should be >= 0.

These negative tile id's up the logic used to remove tiles from the
cache.  When identifying tiles for removal, we look for the furthest
tile away from us by starting out the furthest id at -1 and if we find
something further, we update the furthest tile id.  Then at the end we
check if the furthest tile id >= 0 to see if we found anything we
could remove.  However, the furthest tile id was these bogus tiles
with negative tile id's so the system always assumed there was nothing
appropriate for removal.  This made it impossible to ever remove a
tile from the cache meaning it quickly filled up and no more tiles
could be loaded.

I fixed the one instance of scheduling tiles for a bogus location, and
added a sanity check so if it ever happens again we'll bomb with an
appropriate error message.

2b056c8452 This set of changes touches a *lot* of files. The main goal here is to
fix startup sequence problems where we initialize the FDM before we know
the desired starting altitude.

These changes delay fdm initialization until the local tile has been loaded
and we can do a real intersection and find the true ground elevation.

In order to do this, I depend more on the property manager as glue, rather
than the FGInterface.

There are some glitches still when switching to a new airport or reseting
the sim.  I will work on addressing these, but I need to commit the changes
so far to keep in sync with other developers.

4a609646b6 Modified FlightGear/src/Scenery. The tile loader thread no longer adds

queue and add any tiles to the scene graph.  I was playing around with
the counter_hack so there might be some commented out code, etc.  I also

b0b6c34249 Initial stab at a threaded tile loader contributed by Bernie Bright.
He writes:

Here are the final changes to add threads to the tile loading.  All the
thread related code is in the new FGTileLoader class.

./configure.in
./acconfig.h
Added --with-threads option and corresponding ENABLE_THREADS
definition.  The default is no threads.

./src/Scenery/tilemgr
Removed load_queue and associated references.  This has been replaced by
a new class FGTileLoader in FGNewCache.
Made the global variable global_tile_cache a member.
schedule_needed(): removed global_tile_cache.exists() tests since
sched_tile() effectively repeats the test.
initialize_queue(): removed code that loads tiles since this is now
performed by FGTileLoader.
update(): ditto

./src/Scenery/newcache
Added new class FGTileLoader to manage tile queuing and loading.
tile_map typedefs are private.
exists() is a const member function.
fill_in(): deleted
load_tile(): added.

./src/Scenery/FGTileLoader
The new threaded tile loader.  Maintains a queue of tiles waiting to be
loaded and an array of one or more threads to load the tiles.  Currently
only a single thread is created.  The queue is guarded by a mutex to
synchronize access.  A condition variable signals the thread when the
queue is non-empty.

CLO: I made a few tweaks to address a couple issues, hopefully what we
have is solid, but now we kick it out to the general public to see. :-)
