[Mono-winforms-list] more gtk look stuff

[Roderick Colenbrander]

The dll uxtheme takes care of all theming. "Real" xp apps use new versions of 
comctl32 and friends in which uxtheme.dll is used as a plugin. Other apps use 
it directly.

The dll takes care of all theme loading and stuff related to that. I'm about 
sure this dll can be implemented using gtk calls and even other api's. The 
opposite of this is already happening with gtk on winxp. Using uxtheme.dll to 
theme GTK ;) Check out gtk-winp.sf.net

Note that uxtheme will need a thread on wine-devel, since it needs some 
changes in a few other dlls. Since the uxtheme dll itself doesn't do that 
much.

Here is some more information of the working of it all:
