** Branch linked: lp:~loic.molinari/qtubuntu/qtubuntu-requested-surface-
format-fix

** Description changed:

- 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.
+ 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.
  
- 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.
