[GEM-dev] svn update break rectangular texture with shader

[Hans-Christoph Steiner]

In audio land, you can count on Pd to give you the exact same stream  
of numbers for the same operations (i.e. determinism).    I don't know  
enough about OpenGL to know if you can count on it to give you the  
exact same stream of numbers for a given set of operations.

If so, you can render a reference image, then to test, make a render  
image, then check it against the reference.
