From f449be660e70aac2aefd2ce84581e137de25520b Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sun, 27 Nov 2011 16:21:02 +0000 Subject: [PATCH] mesa/format: add mesa MESA_FORMAT_ARGB2101010_UINT support. This format is used in the ARB_texture_rgb10_a2ui spec. It adds core mesa support, texformat + texstore support, format_unpack and fbobject.c (all patches from list merged + fixed up). also fixes some whitespace issues.
