opengl's drawBitmap() should also scale properly if needed (tdf#123372)
If the bitmap to be drawn will need to be scale for drawing, OpenGL
handles this by scaling, but the scaling is of poor quality. Other
backends scale in such a case with a good quality, and e.g. opengl's
drawAlphaBitmap() also does the same check, so copy that check
to drawBitmap() as well.
