Bug Description

QPlatformIntegration::createOpenGLContext() and QPlatformIntegration::createPlatformWindow()are given a QSurfaceFormat describing the format (and other options like the swap interval) requested by the user. This is currently ignored by QtUbuntu which always creates an ARGB8888 context and an ARGB surface.

Telling mir whether the requested surface is opaque or not allows compositing optimization by rendering opaque surfaces front-to-back with depth write/test on (early z-culling) and blending off.
