DescriptionMerge 65982 - Downsample thumbnail by powers of two before doing lanczos
This speeds up the resizing portion of thumbnailing from 40ms->15ms on my linux z600 at nearly fullscreen resolution. Thumbnail resizing times on weaker hardware (like netbooks) has been observed in the 150ms+ range, so hopefully this is a proportional speedup there as well.
