This is the way it was done for gtk vs. gtk2, but the bug has been
updated since I first read it (over 24 hours ago) and apparently
the Gnome team don't want the two separate flags in the future.
I'm not really a gtk or Gnome (or X11) user, so I don't really know,
but the two separate flags did strike me as a bit of an ugly /
clumsy way of doing things.
It's also the only mechanism I know of to do it.
If the ebuild will support two toolkits and the choice of which to use
is based solely on a user's preference, there is only one way to
resolve that - a precedence list. There's no way around that.
There's also mutually exclusive USE flags (there's an eclass for that),
which is what the submitted patch did.
