From Richard:

Cleanup of shape code:

i) Remaining minodr code from TGLSceneObject moved to TGLLogicalShape or
derv. shape classes.

ii) Remove obsolete TGLSceneObject class.

iii) Move shape classes (TGLFaceSet etc) to own .h/.cxx + now derv. from
TGLogicalShape directly

Plus other minor tidying up.

WARNING!!
if you check-out from CVS, do
rm gl/src/G_*, gl/src/*.o
make
