This did random things with some image formats, including 10 bit formats. Fixes the mp_image_clear() function too. This still has some caveats: - doesn't clear alpha to opaque (too hard with packed RGB, and is rarely needed) - sets luma to 0 for mpeg-range YUV, instead of the lowest possible value (e.g. 16 for 8 bit)
