From 0756dc876c01a3d07da34e2da1899b340b0fb819 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Mon, 9 Mar 2009 12:17:28 +0000 Subject: vbo: stricter checks on Driver.NeedFlush This variable is being used in the r300 driver to trigger a flush under circumstances unrelated to the use in the vbo module. Tighten up the checks in vbo so as to avoid conflict with r300.
