It works well for my purposes, and I find it a quite convenient tool to work
with - even for doing animations.

True. Well, I could try to do some reworking of the patch to integrate it into
the --show-layers= option instead. The only thing that would worry me then is
that the option can be hard to understand in the start since it comes in many

--show-layers=background,2-4,image
