Public bug reported:

QPlatformIntegration::createPlatformWindow() is given a QWindow with an
associated QSurfaceFormat describing the surface format (and options
like the swap interval) requested by the user. This is currently ignored
by QtUbuntu which always creates an ARGB8888 surface.

On top of that, it should also tell Mir whether the requested surface is
opaque or not and allow compositing optimization by rendering opaque
surfaces front-to-back with depth write/test on (early z-culling) and
blending off.

** Affects: qtubuntu (Ubuntu)
