From b980b2eeb62dc48101a7481d02d196c80b9da397 Mon Sep 17 00:00:00 2001
From: Keith Whitwell <keith@tungstengraphics.com>
Date: Mon, 8 Jan 2001 04:09:41 +0000
Subject: [PATCH] Add a 'RenderPrimitive' callback to t_vb_render.c.  Helps out
 drivers that used to require a 'ReducedPrimitiveChange' callback.

Various compilation fixes for XFree86.

Reverted to the older version of glcore.h used internally in XFree86, and
moved it to 'Mesa/include/GL/internal/glcore.h', for compatibility with
XFree86.
