From 8c41c757fe8efa04df0dd5cdfb33a75b84891c19 Mon Sep 17 00:00:00 2001
From: Ian Romanick <idr@us.ibm.com>
Date: Tue, 15 Aug 2006 16:47:34 +0000
Subject: Add support for GL_EXT_gpu_program_parameters.  Any driver that
 enables either GL_ARB_vertex_program or GL_ARB_fragment_program should enable
 this extension as well.
