//  OpenThemeData()     - Open the theme data for the specified HWND and

//
//                        OpenThemeData() will try each class name, one at
//                        a time, and use the first matching theme info
//                        found.  If a match is found, a theme handle

//                        a "NULL" handle is returned.
//
//                        When the window is destroyed or a WM_THEMECHANGED
//                        msg is received, "CloseThemeData()" should be
//                        called to close the theme handle.

//                        If a match is found, OpenThemeData() returns a
