From b8906adb66294e629aba58668a1851ac3fdaa391 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 6 Feb 2013 17:03:49 -0800 Subject: intel: Allow blit readpixels even when the pack alignment is set. The default alignment is 4, so this fast path was rarely hit. Rather than introduce logic to handle alignment, just use the Mesa core function.
