My goal is to write a bridge or adapter for Gtk2::Ex::MindMapView so 
that I can use code other than Gnome2::Canvas since libgnomecanvas has 
been deprecated. From what I can tell there is no ready-made solution in 
perl yet. Is this correct? Does the Gtk2-perl team have plans to replace 
Gnome2::Canvas with another canvas?

As I see it, I am left to either:

a) Write my own canvas in perl (possibly using Cairo or OpenGL).

b) Write perl bindings to goocanvas or criawips or some other C canvas.

c) As Torsten pointed out, contribute to the existing efforts.

d) Wait and see what happens.

At the moment I'm unclear as to which approach to take as I'm relatively 
new to Gtk and don't know xs. I'm trying to understand the degree of 
difficulty of the various approaches and what it might make sense for me 
to do.

Any opinions on what direction to take with this difficult problem are 
appreciated.

In the mean time I will take a closer look at the existing efforts.
