This should be fixed now on the emacs-29 branch.
It isn't perfect: "i -" leaves display artifacts (which I think are
unrelated to this bug report per se), and "i r" doesn't really work,
except when you type 'r' 4 times in a row. But I'm not sure I
understand the conceptual meaning of rotating a sliced image, and even
resizing it doesn't necessarily have a clear-cut meaning IMO.
Perhaps we should decide we don't support these operations for sliced
images, and simply show a different error message specifically about
that non-support?
Lars, any comments and/or ideas?
