Because gtkrc lets GTK+ apps customize things like this per-widget. That
may be why wxGTK doesn't even _try_ and just returns the value of 15.
Now, this can be fixed under the assumption that all scrollbars will be
the same in an app, but it wouldn't be 100% correct. That's probably OK,
though.

Same problem: dummy window is not necessarily the real thing.
