okay, that wasn't so bad

So while I did have to implement an iterative font sizing method, it wasn't as ugly as I thought it would be. And, since it's currently only used for button text, which is relatively static, it shouldn't be a horrific performance hit to run it only at startup (or when changing button labels).

so, as of this writing, wotsam's got buttons that change color when you click them, have rounded edges (though the edges don't look right and probably need to be investigated), and have a caption that automagically gets the right sized font.

and to think i'm not a ui programmer by trade. how can that be? oh, right, it's because i always come up with ugly uis.
