correct comctl32 implementation

[Andrew Green]

I'm not sure how it will only use theming for version 6 without sxs. Will
the control have to manually check the manifest?

I am a bit familiar with how to use the themes to draw controls and that
shouldn't be an issue.

At the moment i'm more confused with this window class redirect thing. I've
been trying to find someone who knows a bit about it. Without much luck.
