Sounds good :-)

As some optimization somewhen we could try pre-generate most of the shader in 
SetFunction and just insert a few values based on the stateblock in 
CompileShader. Something like storing offsets / pointers into the char[] 
array which contains the glsl / arb string where a "1" / "2" / "3" or "cube" 
has to be inserted, or comment marks added / removed. The actual GL 
compilation still needs to be done during draw though.
