need some selection and dnd code

["muppet" <scott asofyet org>]

i'm looking at writing bindings for the selection and drag and drop functions
for gtk2-perl.

unfortunately, i have not use these APIs before, and so have no sense of
what's a normal usage and how the stuff should be wrapped.

so, if anybody could give me a primer on X selections and drag and drop in
Gtk, preferrably with some working C code, i'd be greatly appreciative.
