Get transparency working by clearing the window surface.
This is duplicated code from the raster paint engine's beginPaint()
function. For translucent windows the previous contents must be cleared
from the backing store before the new content is painted. This class
should probably be re-written as a subclass of the raster version. The
reason we cannot use that implementation directly is because we cannot
use QNativeImage because it doesn't provide anywhere we can do locking.
