From efde74c89dd8596b4cc0dfd9601e55832833f20e Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Tue, 23 Dec 2014 12:28:29 -0800 Subject: i965: Consolidate some of the intel_blit logic An upcoming patch is going to introduce some code here, and having this code organized as the patch does makes it a bit easier to read later. There should be no functional change here.
