Yes, I think so.  I haven't actually tried this, but I think it should
be possible...

If the images are large, then this may be slow, but it shouldn't
generate a lot of garbage (since the image data itself in (in case of a
"data" image) should be shared, still.  I think it's worth a try, at
least.  If it turns out to be very slow, then we can start thinking
about mechanisms for marking specific (smaller) icons for rescaling,
while leaving the rest of the images alone.
