I want to be able to specify "center" or "midbottom" for the sprite anchor without knowing the image's dimensions. And I want that anchor point to remain in the appropriate place even if the image is rotated, scaled, or flipped. I'm not sure that an offset would accomplish this, but if so, then that's okay.



I agree, what I suggested is that both things should be possible: a general offset and/or specifying 'center' or 'midbottom' or....

I'm not sure right now how the math to maintain the point at the appropriate place. Maybe this needs some more specification for the different transformations (rotation, flip, scale).
