From d13ab69a78acd8ab538758c0f4cdd702d2c98939 Mon Sep 17 00:00:00 2001 From: Scott D Phillips Date: Tue, 9 Jan 2018 23:16:58 -0800 Subject: i965/tiled_memcpy: change linear pointer from (0, 0) to (xt1, yt1) In all current uses, the linear surface is only allocated starting at (xt1, yt1) anyway, so this improves the calling ergonomics.
