Resize images in animations *without* scaling
Keynote's animations allow you to resize objects (e.g. shapes) by scaling — i.e. having a shape grow or shrink during presentation, while keeping its aspect ratio constant; but what if you want to just specify the final dimensions yourself, such that the shape's aspect ratio is *not* preserved? Is there any way to, e.g., have a rectangle seamlessly transition into a square (or vice versa)? I'd be so surprised if this weren't possible, but I can't seem to figure out how to do it.
