/**
 * These are basically just wrappers/adaptors for calling the
 * ctx->Driver.foobar() GLSL-related functions.
 *
 * Things are biased toward the OpenGL 2.0 functions rather than the
 * ARB extensions (i.e. the ARB functions are layered on the 2.0 functions).
 *
 * The general idea here is to allow enough modularity such that a
 * completely different GLSL implemenation can be plugged in and co-exist
 * with Mesa's native GLSL code.
