Ensure raster pixmap cache key is the same as that of pixmap.toImage()

This is done to support texture uploads in an image provider. It ensures
we can load the texture using QImage in the image provider, and when
it is later painted as a pixmap, the cacheKey will be identical
(assuming no format conversion was required).
