[Bug 30173] allow separate python-gnomecanvas package

[Jani Monoses]

Public bug reported:
https://launchpad.net/malone/bugs/30173

Affects: gnome-python python-gnome2 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
it would be nice if the bindings were more fine grained, like the ruby gnome bindings, so one could only install python bindings to gnomecanvas without the rest of the gnome bits, since libgnomecanvas does not depend on other gnome C libraries.
python-gnome2 would then additionally depend on the broken out packages.
