Similar to and inspired by glimagesink and gtkglsink. Using the Wayland buffer transform API allows to offload rotate operations to the Wayland compositor. This can have several advantages: - The Wayland compositor may be able to use hardware plane capabilities to do the rotation. - In case of pre-rotated content on rotated outputs the rotations may equal out, potentially allowing the compositor to use hardware planes even if they don't support rotate operations.
