Partly based on the _ThemeHelper struct in MFC7.0 source code (winctrl3.cpp),
and the difference is that this implementation wraps the full set of
visual style APIs from the platform SDK August 2001

Changes made by Jim Crafton to make things fit in better with VCF existing code
and to make it easier to read/understand what's going on.
