4) Theme all widgets with a hard link to uxtheme but have a "Win98 look"

Well, to be strictly like Windows then I guess we could actually build
comctl32 twice with #ifdefs etc for the theming code.

That sounds rather complicated and like it might introduce further bugs
when apps don't expect controls to be already subclassed...
