A few minor tweaks to make "non-alternative window look" at least tolerable. It is not quite what I wanted to do, but at least it degrades nicer than before.
Also fixed up a few default preferences of Look Enhancements. I'm really liking square corners these days so that is the default on windows, but can be modified locally by the user. Also I am bringing back gradient scrollbars as the default based upon user feedback.
I think this is all I will be doing until this package is integrated into Squeak 3.9. (maybe ;-).
