From 22b116171f88f2dcb1be2a5ea6cd64c0731670e9 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 3 Apr 2017 04:43:15 +0100 Subject: [PATCH] radv: fix interp at sample code. Interp at sample needs to use the center, since the sample positions it retrieves are relative to the center. This fixes a bunch of CTS tests with multisample_interpolation.
