// class RxCaption
//
// Generic caption painter. Handles WM_NCPAINT, WM_NCACTIVATE, etc. to
// handle drawing custom captions. To use it:
//
// - call Install from your frame's OnCreate function. 
// - Set a custom CaptionBackground if desired
// - Set custom TextAttributes if required
//
//	 Derive from this class for custom caption layouts.
// 
//   If you are drawing custom caption buttons, you must handle WM_NCLBUTTONDOWN & co.
//   yourself. RxCaption does not handle the mouse for custom caption buttons.
