Both work fine if I simply drop them into a 4.5 image. I can move/rotate/scale no problem. Shadow rendering is not nice, but that's a problem of the shadow renderer, not the bitmap itself.

Which suggests that the PNG importer is not, in fact, broken.

Additional touchup work should be done in Scratch, if it needs these pictures to be in some special format.
