blitter: Base QBlitterPaintEngine on QRasterPaintEngine
The original intention was to identify a clipping bug, it turns out
that during a ::begin() (and systemChanged) we should forward the
QPaintEnginePrivate state to our proxy engine.
Instead of using the proxy-pattern subclass rasterengine and
specialize the paths we are able to accelerate using the blitter
interface. This will avoid similiar problems in the future. I have
no performance measurement to show which of the two approaches is
faster/slower.
