From dd63fa28f14f8ddeeeca1847eb7d38f4e2bc2234 Mon Sep 17 00:00:00 2001 From: George Kyriazis Date: Mon, 14 Mar 2016 17:40:14 -0500 Subject: gallium/swr: Cleaned up some context-resource management Removed bound_to_context. We now pick up the context from the screen instead of the resource itself. The resource could be out-of-date and point to a pipe that is already freed. Fixes manywin mesa xdemo.
