[pygtk] Good way to determine which version of PyGObject is installed

[Simon Feltman]

Versioning seems a bit convoluted at the moment. If you are looking for
specific Gtk+ features based on version (not pygobject features) use the
Gtk+ library versions (Gtk.MAJOR_VERSION, Gtk.MINOR_VERSION,
Gtk.MICRO_VERSION)

PyGObject is only providing overrides for the gtk+ typelib, so I would not
necessarily rely on pygobject versioning for anything being pulled in
through the gi.repository. GObject and Gio are part of GLib, and you can
access the version of those with:
(GLib.MAJOR_VERSION, GLib.MINOR_VERSION, GLib.MICRO_VERSION)

Unfortunately, do to the Gtk overrides currently being delivered with
pygobject, there may be Gtk override updates tied to specific pygobject
versions. Depending on what you are trying to achieve, a more robust
technique might be to use "hasattr" for checking if something is available.
