From 9b75627fab5bf2ea90f27ddd31b60c54895f6de6 Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Wed, 15 Apr 2009 15:53:34 +0200 Subject: gallium: Make sure we flush before some texture / buffer operations. Also implement context member functions to optimize away those flushes whenever possible.
