add model animation support
increase number of allowable bone matrices, remove warning abount animations beind unhandeled, indentation
increase number of allowable bone matrices
ogl3-assimp: Change initial rendering style from textured to diffuse (so that untextured models aren't drawn as solid black
typo; black->back
use MAX_BONES variable consistently
Prevent warnings about bone-related uniform variables being missing from programs
print helpful error message if GeomTransform is not used in the vertex program correctly
If a texture is not set in kuhl_geometry, draw the geometry without a texture (previously we would use whatever the currently bound texture was.
improve comments and cleanup code related to model animation
misc code cleanup, write a single aiMatrix4x4->mat4f function and use it
cleanup code; fix memory leak
add kuhl_load_model_file_ogl3() to load a model without drawing it; add kuhl_model_file_aiScene() to give the programmer access to the aiScene object for a model
clarify that textureDirname parameter is sometimes unused in some of the model loading functions
Fix some issues with doxygen documentation
Modify ivs.sh script to check if tilenodes are accessible before we try to start the program
add add extra dgr calls to make ogl3-assimp character animation work on IVS
add additional check in ivs.sh to ensure that all tiles are acessible
make both the two ivs scripts more consistent with each other
ensure bind pose is used by programs that do not call the 'update model file' function
