From 6f3d91840945fbd9221a247e4f95b32c4051f202 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 15 Feb 2012 15:29:29 -0700 Subject: [PATCH] mesa: add missing texture integer test in glTexSubImage() If the texture format is integer, the incoming user data must also be integer (and similarly for non-integer textures). NOTE: This is a candidate for the stable branches.
