Subject: evas_object_image: Track whether an image object supports direct scanout
X-Git-Tag: upstream/1.20.0~449
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3965a663ccb498baf04f1089fea388011168c2c0;p=platform%2Fupstream%2Fefl.git

evas_object_image: Track whether an image object supports direct scanout

If an evas object is a wayland dmabuf, uses native surface 5 or higher,
and has a scanout handler set, then it meets the basic requirements for
placing on a hardware plane.
