Wine integration with native (Gtk, Qt, Cocoa/Carbon) themes

My whole point is maintenance and distribution. Sure you could create different plugins for uxtheme but the language limitation won't allow such plugins to enter Wine. They would need to be maintained outside of Wine which would be bad. It has risks of bitrotting and second it would be a pain to package it all. I don't think we want such components maintained outside of Wine.
That all is the reason for having a 'winetheme' app which creates .msstyles themes and which uses GTK/QT/Cocoa as I think Alexandre could perhaps live with this as we wouldn't pollute any Wine dlls with 'bad' languages. But as I said this approach would require syncing themes at Wine startup and theme refreshing wouldn't work without some evil polling mechanism. Personally I wouldn't find this switching at runtime important though and I wonder if our dlls support this at all. (That would have to be fixed then but personally I don't give it a high priority)
