Issue set_opaque_region on opaque surfaces
The application will tell Qt whether the background is transparent
through either Qt::WA_TranslucentBackground or QQuickWindow::setColor.
These will set a QSurfaceFormat.
This change checks the QSurfaceFormat and issues the opacity information
so we can properly implement culling optimizations in the compositor.
