From 6d460af6af77a0d5a5b568bcd6094b98e249ba93 Mon Sep 17 00:00:00 2001
From: Brian Paul <brian.paul@tungstengraphics.com>

Subject: Added ctx->Vertex/FragmentProgram._Enable flags.  Set when
 vertex/fragment program is enabled AND the currently bound program is valid.
 Check _Enable instead of Enable to prevent things from blowing up when
 someone calls glEnable(GL_VERTEX_PROGRAM_ARB) without actually defining a
 program.
