  32  * These are basically just wrappers/adaptors for calling the
  33  * ctx->Driver.foobar() GLSL-related functions.
  34  *
  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).
  37  *
  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.
