101	Use DIVE  to speed up blitting in QRasterWindowSurface	Dmitry A. Kuminov		"We may want to try to use DIVE to speed up flushing the widget's raster buffer to screen in QRasterWindowSurface::flush().

Currently we use GpiDrawBits() for this purpose which is not very optimal since the image bits aren't likely to go directly to the video memory in this case.

We also may provide a custom QWindowSurface that allocates widget buffer directly in video memory (I recall DIVE should allow this)."	enhancement	closed	major	Qt 4.6.2	QtGui	4.5.1 Beta 3	highest	fixed		pmw
