Currently in WCS mode, ImageCrop only works when the celestial coordinates are aligned with the image coordinates: declination along the vertical axis and right ascention opposite to the horizontal axes. This is the standard alignment for processed survey images, but very inconvenient when using single exposure images that are not yet aligned.

So we have to remove the WCS mode's assumptions regarding the orientation of the WCS axeses to fix this problem. When there are multiple images to stitch from, we have to simply make sure that the axises align with each other, not with the image axises.
