[GEM-dev] bug: geos vertices messup with draw full/fill message

[chris clepper]

Actually, to be more correct, all Geos are not created equal.  Certain 
Geos, like sphere and cylinder, use a a library called GLU which 
handles everything about drawing those shapes.  The others are rolled 
by hand by the GEM developers.  The main difference is that the two 
types have different base classes.  The drawing types are not the same 
between them, which is why GL_QUADS doesn't really do anything.  I 
don't know if that's even supported by GLU as it's not really an 
appropriate mode for those shapes.

Perhaps there should be a tutorial or help patch explaining this...
