It was quite easy to create Tk::CanvasFig which was approximately the
same task: turning the contents of a Tk::Canvas widget into another
vector format intended for printing, in this case the file format of
fig/xfig (but svg or pdf wouldn't be hard either). The introspection
abilities of Tk::Canvas are complete, and allow one to do such a
thing. But it's surely more difficult to create a similar
module/method with Tk::Zinc because of its heavier feature set.
