Author: Brian Paul <[email protected]> Date: Mon Jun 18 10:22:06 2012 -0600 svga: fix synchronization bug between sampler views and surfaces This fixes a bug where a sampler view was using stale texture/resource data when the texture was modified through a surface (render to texture). Bumping the texture and layer ages triggers sampler view revalidation. Fixes piglit fbo-blit failure.
