evas-wayland-shm: Refactor Evas Wayland Shm Engine (Fix T2201)
Summary: This patch set fixes the issue of Evas wayland shm engine causing crashes when resizing efl apps in the E wayland compositor. It refactors the evas engine to wait for release events on buffers, and hooks into frame callbacks so that release events will get triggered at the appropriate time. @fix Signed-off-by: Chris Michael <cp.michael@samsung.com>
