hmm, last time I checked, plugins run in a different process space, so
setting up callbacks is a bit more difficult than normal. There are a
coupla schemes that could work, including copying the args into shared
memory, and telling the plugin to invoke the process, RMI over a unix
socket, etc, however, the gimp process can't just invoke the callback in
the plugin as though the plugin was a shared lib.
So, to answer your qestions, no, it is not straightfoward, yes, there is
a gotcha but yes, it is possible.
