Even simpler.

Now that I've got Cairo working, I'll should soon be able to release a 
version of Gtk2::Ex::Geo, which is (almost) pure Perl. It will define a 
framework for geospatial data viewers (including overlaying data) and 
applications. I've got Gtk2::Ex::Geo:: classes which subclass Geo:: 
classes, which link to serious geospatial data libraries, but it should 
and will be possible to use Gtk2::Ex::Geo without them.

The most interesting widget is Gtk2::Ex::Geo::Overlay, which is a 
subclass of Gtk2::ScrolledWindow, and implements a kind of geo canvas 
for visualizing geospatial data and handling user interaction with that 
data (zoom, pan, select, query).

The almost part comes from the fact that I need to create and manage the 
cairo surfaces and gdk pixbufs a bit in xs so that I can exhange them 
with C routines. But that should be minimal.

Cheers,

Ari
