[plt-scheme] MysterX varargs, ImageMagick

The following thread:

http://list.cs.brown.edu/pipermail/plt-scheme/2003-July/thread.html#3206

suggests that in order to use ImageMagick via COM, MysterX needs to be
fixed to work with vararg methods. Both Anton and Joe mentioned being
willing to work on it.

Has any progress been made? This would be very helpful to me. Y'all
probably can't even imagine how mind-bogglingly broken the Gimp's
scripting language -- which is referred to as "Scheme" in what I can only
ascribe to cosmic coincidence -- is.

Thanks,
Dave
