cc: Use medium filter quality for downscales.

This patch makes us use a medium filter quality if one of the dimensions
of an image is being downscaled. There are a couple of things to watch
out for:

1. This may cause worse quality on some images
2. This may regress memory, since mips are larger cache objects than
   specific smallest size.
