Working plumb of image scaling:
1) always generate mipmaps if we detect that we are downsampling.
2) pre-scale the image if we detect that we are upsampling
(currently valid for scale+translate only)
3) A few miscellaneous bug fixes related to image scaling.
Still need SSE/Neon versions of these image scalers.
