This also fixes distortion weirdness in the osgviewer version. That
was caused by osg::GraphicsContext getting in the act on resize events
and adding its own scaling to the projectionOffset of slave cameras!
The LOD far range on the tile entry scenegraph node was initialized to
0. This meant that any traverals of active children that happened
before the tile manager updated the node would ignore the node
altogether. Among these is the groundcache traversal which was failing
at startup even though scenery was loaded.
Also added a function to dump scene graph nodes to files; very handy
in gdb.
Make an OSG file reader for .stg files.
New class flightgear::SceneryPager, which is a subclass
osg::DatabasePager to handle explicit delete requests.
Modify FGNewCache, FGTileEntry, and FGTileManager to use
SceneryPager. Mostly this involved removing the queues that talked to
FGTileLoader.
Calculate accurate tile timestamps from the time they are traversed in
the cull stage (which means that they are visible) instead of updating
them periodically.
Replace tile entry transform and range node with one LOD node
are not available out-of-the-box on all systems and keyboards, and should
therefore not be used in files committed to CVS. This makes them well
suited for local key bindings, as they aren't likely to get overwritten
with later releases. SDL supports Meta and Super, OSG supports only Meta,
and GLUT supports neither.

This uses the osgViewer infrastructure instead of setting up and osg::SceneView.
When the same change is made for glut, much of render.cxx can be deleted.
file. Possible uses of this functionality could include converting the
model to some other format or coordinate system for use in some other
visualization or simulation.
This is required to make sure the same letter key gets released,
which got the press event. (After Ctrl-press -> a-press -> Ctrl-release
a-release we want the Ctrl-a binding released, not the a binding.)
- add key listener interface for direct key access from Nasal space
This removes some jitter in cases where Nasal is used to set up view
parameters from FDM data, such as position and orientation. (The event
subsystem handles Nasal's settimer() calls.)
This was correct in the old repository and in revision 1.1 of the new,
but then broken in revision 1.2. After that, "lookat" and "lookfrom"
mode used different coordinate systems, and the "Adjust View Distance"
didn't work correctly in "lookat" mode.
"I have been investigating the Concorde IVSI problem. I came to the
conclusion that the trouble is that the environment altitude and thus
the pressure (which is calculated from that) is lagging by 1 frame.
Normally that wouldn't be a problem, but the IVSI calculates rate of
change and it will use the new dt with the old value difference,
thereby arriving at bad results if dt changes (and it does)."

* Delete ai list objects in ~ATC/AIMgr.cxx:AIMgr::~AIMgr()
* Delete colors in GUI/new_gui.cxx: NewGui::~NewGui.cxx
* Delete memory allocated to the class member "route" in
Instrumentation/gps.cxx
* Delete all globals (except a few "unsafe" ones that still cause segfaults
and need further examination.
* Use an SGShared pointer for navaid memory allocation, so that pointers to
individual navaid objects can be included safely in multiple navaid lists
them under /sim/presets/ but they aren't save there, and as fgInitPosition
and its subroutines overwrite them, we lose the information about what the
user really wanted. This is a temporary solution -- it really belongs into
options.cxx.
Turn OPENSCENEGRAPH_MAJOR_VERSION, OPENSCENEGRAPH_MINOR_VERSION and
OPENSCENEGRAPH_PATCH_VERSION into a single number for comparisons in the
preprocessor.
