This doesn't seem like an ideal way of doing this.
I don't see any precedent for this approach in the Swing implementation.
We need some method that is more about the properties of a L&F rather than
keying off name.
Please look around at LookAndFeel and UIDefaults (etc) for a place you could
store a property that tells you what to do.
Or perhaps you this "altProcessor" would be the value you retrieve and if it is
non-null you install it.
Or perhaps this should be pushed down to the GTK L&F
I don't know what the right answer is, I just don't think this approach is it.
