AVFoundation: Remove QVideoSurfaceCoreGraphicsPainter
This was a leftover from Qt 4, as it is no longer possible to use the CoreGraphics paint engine. Instead we should just use the logic in QPainterVideoSurface render the QVideoFrame. Change-Id: I7e97fe7c30fd478dcd405d300e0c3f70050ca25f Reviewed-by: Christian Stromme <christian.stromme@digia.com>
