"Changes to provide rudimentary support for OF 15.8 light point
animation palettes. This change also includes light point palette override
support for external references. This is the last of my code changes to
support OF 15.8 in the flt loader. Barring bugs, of course, knock on wood.
The gist of the animation palette code is to create ref_ptr'd
osgSim::BlinkSequence objects for each palette entry, and then pass them on
to osgSim::LightPoint for any OpenFlight light points that reference that
palette entry. This should be conservative of memory (not that I expect the
animation palette to be extremely large)."
point appearance palette to the OpenFlight loader. Both are 15.8 features.
I also added parsing/comments regarding other things that have changed for
v15.8."
PositionAttitudeTransform, removed the equivialnt callbacks once found in these
transform classes.
Changed the NodeCallback class so its derived from osg::Object instead of
osg::Referenced to allow it to be saved out in the .osg format.
Added support for Update and Cull callbacks into the .osg file format.
Added support for AnimationPathCallback into the .osg file format.
