if the station is too far away. Instead, simply return the closest station.
All the code that searches navaids does it's own range checking anyway.
This will make the navlist query functions a bit more useful for other
types of functionality where you may need to lookup a station without
consideration of range (i.e. presetting your position relative to a navaid.)
hemisphere the distance is positive, if you are in the departure hemisphere
the distance is negature. (Possible use for graphing approach distance
vs. glide slope or cdi.)
Some more cmall changes to the SimGear header files and removed the
SG_HAVE_NATIVE_SGI_COMPILERS dependancies from FlightGear.
I've added a seperate JSBSim patch for the JSBSim source tree.
Ensure that if a condition for a panel mouse binding fails, other
bindings for the same area will have a chance to run.
Add a repeatable flag for panel mouse bindings (defaults to true).

OK, this turns out to be a trivial fix, although I still think it's a
driver bug. There are two calls to glPolygonOffset in the panel
rendering code (shared by both 2D and 3D panels). One is called
per-layer, and sets up a layer-specific offset. The other is called
for drawing the background textures, to lift them off of any
underlying cockpit geometry.
I was using different "factor" values for each, incorrectly. Patch
attached. It was affecting only 2D panels because the 3D ones don't
use background images.
Problem is, by my reading of the specification the bug should have had
the effect of pushing the background texture *farther* behind the
instruments, instead of pulling it on top of them. Either I'm reading
the spec incorrectly or ATI has inverted the sense of the factor
argument. Dunno, I'll submit a bug report to them and see what
happens.

It's actually an astoundingly good idea, and implementable over lunch
to boot. :)
Try the attached patch, which predicates the boxes on the
/sim/panel-hotspots property. I mapped a toggle event on this to a
spare joystick button, and had fun. :)

avoid having the 2D instruments obscure 3D objects in front of them):
It's related to depth buffer precision. On my Geforce cards (2MX and
3), it never happens with the 24 bit depth buffer you get by default
at 32bpp. At 16bpp, it picks a slimmer depth buffer (probably 16 bit)
and the texture layers bleed through.
The code is using a pretty big argument to glPolygonOffset, and I've
never investigated how small it can be. If someone has a little time
the next time they see this issue, try changing the value of
POFF_UNITS at the top of Cockpit/panel.cxx. Decrease it until the
textures *just* start to interfere with each other, and post the value
that works for you.
The biggest and coolest patch adds mouse sensitivity to the 3D
cockpits, so we can finally work the radios. This ended up requiring
significant modifications outside of the 3D cockpit code. Stuff folks
will want to look at:
+ The list of all "3D" cockpits is stored statically in the
panelnode.cxx file. This is clumsy, and won't migrate well to a
multiple-aircraft feature. Really, there should be a per-model list
of 3D panels, but I couldn't find a clean place to put this. The
only handle you get back after parsing a model is a generic ssg
node, to which I obviously can't add panel-specific methods.
+ The aircraft model is parsed *very* early in the initialization
order. Earlier, in fact, than the static list of allowable command
bindings is built in fgInitCommands(). This is bad, as it means
that mouse bindings on the instruments can't work yet. I moved the
call to fgInitCommands, but someone should look carefully to see
that I picked the right place. There's a lot of initialization
code, and I got a little lost in there... :)
+ I added yet another "update" hook to the fgRenderFrame routine to
hook the updates for the 3D panels. This is only required for
"mouse press delay", and it's a fairly clumsy mechanism based on
frame rate instead of real time. There appears to be delay handling
already in place in the Input stuff, and there's a discussion going
on about different mouse behavior right now. Maybe this is a good
time to unify these two (now three) approaches?
really see anything different in the day, but as day turns to night the
panel smoothly darkens and the lighting component becomes visible.
Lights are wired to electrical system so if you kill power, you lose the
lights.
- Removed some old cruft.
- Removed some support for older versions of automake which technically was
correct, but caused the newer automakes to squawk warnings during an
initial sanity check (which isn't done very intelligently.)
NOTE: this fix is technically not correct for older version of automake.
These older version use the variable "INCLUDES" internally and could have
them already set to an important value. That is why we were appending
our values to them. However, newer versions of automake don't set this
value themselves so it is an error to append to a non-existant variable.
We seem to "get away" with overwriting the value on older versions of
automake, but if you have problems, consider upgrading to at least
automake-1.5.
- tidies up the update-time-step handling (making it a simple "dt");
- makes the altimeter get a proper pressure, and the (unused) vacuum
calculation get a proper RPM (*);
- replaces property name look-ups with static pointers to property nodes.
Notes from DPM:
- the static pointers are a very bad idea, but they're only temporary;
I plan to make FGSteam into a proper subsystem soon, and then they
can be member variables
- I fixed the patch to get the current static pressure from the
/environment/pressure-inhg property, so that the altimeter interacts
properly with FGEnvironment
