[Mesa-dev] [PATCH] egl/wayland: Set __DRI_IMAGE_USE_SCANOUT for shared buffers

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

The compositor may have the hardware scan out directly from the buffers
sent by the client, so we must make sure the buffers we create are
suitable for scanout.
