could you possibly implement cropping routines similar to avisynth's resizers? these allow precise (subpixel) cropping of the image which is necessary in all manner of video resizing applications (ie field alignment, correct 702 width scaling from and to HD, etc).
Definitely planned.

A while ago I read a study that did an automated comparison of various dithering techniques, including all common error diffusion patterns and even randomized ones. It concluded that while the Floyd-Steinberg pattern was near perfect for regular scanning, it was actually sub-optimal for serpentine scanning. The pattern I'm using tested best in its class, outmatched only by a slow and complicated edge-directed binary search algorithm.

I tried it out myself on a few handfuls of images and found that it did help avoid certain bad patterns, so I stuck with it.
