From 7dd93291cad743e83e972a323a5775ff5a954bd5 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 7 Jul 2014 17:24:42 +1000 Subject: ui/sdl: Support shared surface for more pixman formats At least all the ones I've tested. We make the assumption that SDL is going to be better at conversion than we are.
