Fix scrolling of QRasterBackingStore when operating on QRasterGLSurface
We were to strict in what surface type we allowed scrolling for. The
RasterGLSurface type is an odd one, used by widgets to compose GL
and raster content, which means we still have a raster backingstore
we can scroll. It's just the flush that's different.
Pick-to: 6.2
