[ros-dev] I think I know how uxtheme works...

[Jonathan Wilson]

We need to support the following: (at some point we do anyway)
1.Manifests, SxS, Activation Contexts etc (not just for uxtheme/comctl32 
6.0 but for other stuff). This includes all the work in user32 to correctly 
support different activation contexts having different versions of the same 
window class like comctl32 6.0 does for the standard controls).
2..msstyles files.
and 3.All the known uxtheme export functions (certainly those documented in 
MSDN and called by apps anyway)
Then, all we need after that is the global hook to do non-client-area themeing

We have to implement this in the same overall way as microsoft did if we 
want to be compatible.
