I am not sure of the interface that should have been setup for
PerlMagick  but the command line, and C MagickCore API
has access to the new  "-layers Composite" operator.

This can compose two lists on images with each other, or a single image
over all the images in the other list.  It can use any -compose setting
as well as take into account   -gravity effects -geometry offsets
and then add to that the normal -page or 'virtual canvas' offsets of
subframes.

See...
  http://www.imagemagick.org/Usage/anim_mods/#composite
for an example..

Only the very latest IM will have these features, and as I mentioned I
am not sure of the API interface needed for Perl or other languages.
