Is there something to just shift/copy an image with subpixel accuracy?
At first I thought that CopySubpix was what I needed, but it only exists for a limited set of single-plane bitmaps. I know there are shifting versions of various transformations, but surely they're all slower than what a simple shifting would be? Or am I missing something?
I can also fake it with a copy & 3 compositing operations, but it's pretty slow too.
