From 7947d05f840cfbb9b162a279d6eccc9416217e68 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Sun, 16 Jul 2017 16:54:44 -0700 Subject: [PATCH] i965: Check if the modifier is supported in select_best_modifier Otherwise, if a client gave us a list of modifiers that contained a modifier we understand but which is not supported on the hardware, we might return that one and then fail to create the image.
