From 04e3969597b485691925dda717e4c986995fdb59 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 24 Jun 2013 14:44:08 -0600 Subject: [PATCH] svga: use new svga_age_texture_view() helper The function does array bounds checking. Note, this exposes a bug in the svga_mark_surface_dirty() function: we're calling svga_age_texture_view() with a texture slice instead of mipmap level. This can lead to a failed assertion. That'll be fixed next.
