I guess that CellRendererText::property_wrap_mode() is only available in
a newer version of gtkmm. I'm not sure, but I guess it was introduced in
gtkmm 2.10.

Although new methods have a "since 2.x" bit in the documentation, I
guess we don't do that for properties. We should.

It's always a good idea to use the documentation for the version of
gtkmm that you have installed, as supplied by your distribution or
installation. The online documentation is the latest documentation for
the lastest gtkmm version.

But only in a newer version of GTK+.
