The Wayland sub-surfaces API is used to embed the video into an application
window.
See Appendix A. Wayland Protocol Specification as the following.
"""
The aim of sub-surfaces is to offload some of the compositing work
within a window from clients to the compositor. A prime example is
a video player with decorations and video in separate wl_surface
objects.
This should allow the compositor to pass YUV video buffer processing to
dedicated overlay hardware when possible.
"""
Added new method gst_vaapi_window_wayland_new_with_surface()
