- remove the SG_GLxxxx_H #defines, since OSG provides its own versions
- this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in
extensions.hxx was pulling in all of Carbon to the global namespace
- very scary. As a result, I now need to explicitly include CoreFoundation
in fg_init.cxx.
- change SG_USING_STD(x) to using std::x
Issues:
- the logic for X11 and Win32 in RenderTexture and extensions is tortured,
please see if you agree I got all the ifdefs correct.
Reduce compiler.h to almost nothing (but it's worth keeping around I think, for
the MSVC and MipsPro warning stuff).
As a result of this patch, simgear/sg_traits.h can be deleted. So can SGCMath.h,
but I'll do that separately.
There is one more 'mechanical' change to come - getting rid of SG_USING_STD(X),
but I want to keep that separate from everything else. (There's another mechnica
l change, replacing <math.h> with <cmath> and so on *everywhere*, but one step a
t a time)
Attached patches remove BORLANDC, and hence SG_MATH_EXCEPTION_CLASH and SG_INCOM
PLETE_FUNCTIONAL from SimGear and FlightGear.
As a result, SG_HAVE_STD_INCLUDES is now *always* set, so I will get the boring
fixes for that done, but separately. I'm still auditing the other things in comp
ilers.h - there's a lot that can die now BORLAND is gone.
"tim recently noticed the database pager was repeatedly loading and unloading
the same objects. he also tracked down the problem to missing bounding sphere
information in osgDB::PagedLOD. this is a simplicistic approach to fix this:
SGPagedLOD will now remember whatever value it sees for getBound() after
loading a child. this patch will make database pager run much calmer."
It turns out that the database pager causes the texture image to be
unloaded after it is applied, so the image and its file name may not
be available for doing the livery substitution. Ask a work around we
set the name of the texture to its file name.
this is a small (-1/+3) patch to fix pick animations on scenery objects.
since picking apparently doesn't care for polygon offsets, the objects
got into the picklist in the wrong way. now, no matter if the "highlight
group" or the "normal group" gets hit first, the callback will fire.
Allows to load submodels with path relative to current model path.
Submodel path must be prefixed by ./ otherwise path is relative to fg_root ( current behavior )

Change the tile light group node mask to traverse VASI lights too.
The change to set the light group node mask to LIGHTS_BITS caused
VASI/PAPI lights to not be displayed during the day. This patch fixes
that and optimizes VASI creation a bit.

model paging patch from Till Busch
Comments from Till:
I started the project at the end of february with a simple idea: move all
3d-model loading to the DatabasePager-thread. my first attempts looked
promising, though they were a little too optimistic (or naive?). the patch
has evolved a lot since.
currently it does the following things:
1. revive SGModelLib, move functions for xml-model-loading there
2. replace all calls to sgLoad3dModel with calls to either
SGModelLib::loadModel() or SGModelLib::loadPagedModel()
almost all models will be loaded by the DatabasePager. the few exceptions are:
your own plane, shared models in scenery, random objects, AIBallistic models.
3. simplify mode-loading functions (avoid passing around fg_root)
4. avoid supurious MatrixTransform nodes in loaded models

constant volume/pitch during the whole lifetime, just *configure*
the sound that way.)

cleanup of precipitation contribution
Reindent everything to Stroustrup style and make member variable style
consistent.
Remove unused header files.
SGPrecipitation is now a subclass of osg::Referenced.
Initialize snow and ice intensity to 0 directly. The methods that set
the intensities change the value slowly and so don't work when the
initial value is garbage.

Cleanup and performance tuning of the random trees code.
The QuadTreeBuilder class was completely revamped as a templated class
to support flexible creation of scene graph quad trees, and a major
bug was fixed as well. Now it actually generates quadtrees instead of
some weird striped thing.
One StateSet is shared among all the "forests." The trees are drawn
after normal terrain objects to minimize some of the transparency
related artifacts.
Lighting was implemented in the ShaderGeometry shader (for both
polygon sides). Ambient-diffuse values for trees are hard-coded in
TreeBin.cxx.
DotOsg wrappers were added for ShaderGeometry so it can be output in
the scene graph dump.

Use node masks and shared state sets to manage ground lights
Do away with the switch in each terrain tile for the ground lights. They are
turned on by node masks now.
Share state sets among all the light nodes and manage the fog values through a
"GroundLightManager" instead of having separate state sets and callback
functions for each group in each tile.
