From 0bbbeba2db0f3fd382d2f591bebc248c5ed40fb5 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 15 Apr 2011 18:15:59 -0700 Subject: [PATCH] intel: Add support for blit copies of >32bpp formats. The blitter only does up 32bpp at a time, so we handle it by mangling coordinates and calling the surface 32bpp. Fixes ARB_texture_rg/fbo-generatemipmap-formats-float with ARB_texture_float.
