35 * Things are biased toward the OpenGL 2.0 functions rather than the
36 * ARB extensions (i.e. the ARB functions are layered on the 2.0 functions).
38 * The general idea here is to allow enough modularity such that a
39 * completely different GLSL implemenation can be plugged in and co-exist
40 * with Mesa's native GLSL code.
