Similar to and inspired by glimagesink, xvimagesink and others. The waylandsink never transform the buffer in any way but delegates this to the Wayland compositor with the Wayland buffer transform API. Rotation and window size are already supported, so this just changes the video surface geometry that is communicated to the Wayland compositor.
