Function Documentation

void GLAPIENTRY _mesa_AttachObjectARB	(	GLhandleARB	program,
		GLhandleARB	shader
	)

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.
