///////////////////////////////////////////////////////////////////////////////////////
// Adding support for XP Styles (Vista Themes) for owner drawn tab controls simply
// does *not* work under Vista. Maybe it works under XP (did not try), but that is
// meaningless because under XP a owner drawn tab control is already rendered *with*
// the proper XP Styles. So, for XP there is no need to care about the theme API at all.
//
// However, under Vista, a tab control which has the TCS_OWNERDRAWFIXED
// style gets additional 3D-borders which are applied by Vista *after* WM_DRAWITEM
// was processed. Thus, there is no known workaround available to prevent Vista from
// adding those old fashioned 3D-borders. We can render the tab control items within
// the WM_DRAWITEM handler in whatever style we want, but Vista will in each case
// overwrite the borders of each tab control item with old fashioned 3D-borders...
//
// To complete this experience, tab controls also do not support NMCUSTOMDRAW. So, the
// only known way to customize a tab control is by using TCS_OWNERDRAWFIXED which does
// however not work properly under Vista.
//
// The "solution" which is currently implemented to prevent Vista from drawing those
// 3D-borders is by using "ExcludeClipRect" to reduce the drawing area which is used
// by Windows after WM_DRAWITEM was processed. This "solution" is very sensitive to
// the used rectangles and offsets in general. Incrementing/Decrementing one of the
// "rcItem", "rcFullItem", etc. rectangles makes the entire "solution" flawed again
// because some borders would become visible again.
