It's quite an interesting suggestion, but it has lots of problems...

That's one of the bigger problems - it won't compile with the standard 
OpenGL headers as they don't define e.g. GL_FRAGMENT_PROGRAM_ARB.
In addition I can't test it as my GeForce3 somehow doesn't suppport 
fragment programs.
In addition this changes nearly the whole file, so in the current form 
it is much too complicated to be applied.
Another point is that this functionality could be implemented much 
better with the glColorMatrix function (which even older OpenGL headers 
define) - if this is acclerated by the GPU as well.
Can anyone give me a hint on this??
