downscaling. This makes quality much better and "at best"
equates to a 16 point sample (2x2 linear interpolation samples,
where a linear interpolation sample equates to a 2x2 sample).
This will have perfomance impact, but the quality is worth it and
makes it closer to software downscaling in quality. It supports
2x2, 2x1 and 1x2 oversampling. YUV not done, nor image mask
(font shaders not needed).
