[GEM-dev] [pix_multitexture] stuff

[james tittle]

hey,

...in current CVS, I've hacked in multitexture support to GemShape's  
SetVertex() call, and it seems to work pretty well...however, sanity  
testing on other machines is always appreciated ;-)  Attached is an  
example patch which allows two movies to be loaded, then combined in  
a later chain and blended/combined/added/whatever else on the gpu...

...main caveat is that this is only support in [rectangle], or other  
geos that use SetVertex() to set texture coords...also, it doesn't  
seem to work with GL_TEXTURE_2D, but GL_TEXTURE_RECTANGLE_EXT seems  
to be standard on cards anyway...
