From f8059c9f3fdd270370737c9eff369eb6d14caa0b Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Thu, 23 Jul 2015 20:18:57 -0400 Subject: [PATCH] mesa: fix error checking for getting zero-sized texture images Commit 17f714836 (mesa: rearrange texture error checking order) moved the width/height/depth == 0 allowance before checking if the image was there. This was in part due to depth having to be == 1 for 2D images and width having to be == 1 for 1D images. Instead relax the height/depth checks to also accept 0 as valid. With this change, bin/arb_direct_state_access-get-textures starts passing again.
