+Subject: [PATCH] dri: add createImageWithModifiers2 interface
+
+With the addition of createImageWithModifiers usage flags were
+dropped, as it was believed at the time that modifers will be a
+full replacement for the usage flags. This has turned out to be
+untrue, as modifiers are not able to describe buffer placement.
+
+Add a new version of the interface, that allows to specifiy
+use flags in addition to the modifier.
