Wayland window transparency

[Giulio Camuffo]

Hi Neal,

You don't need to use any Wayland or Weston specific thing. Wayland
compositor just use buffers you provide to them as you provide them,
so if you want the buffer to be opaque give Wayland an opaque buffer.
Either use one without an alpha channel or clear the whole buffer with
an opaque color before drawing your application content.
