ScaledImage results in squishing at small sizes in 1.13.1

So I just updated to the 1.13.1 SDK, and an image I use is now looking squished. It seems like it's due to calling image:scaledImage, and only when scaling it fairly small. For example, it looks fine when calling image:scaledImage(.04) but not image:scaledImage(.03) or smaller. Interestingly, at .03 and .01 it squishes horizontally, and at .02 it squishes vertically.
