If you use "GetCharacterPlacement" 
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/fontext_4l84.asp), 
you will get the following:
1. A list of pixel offsets for each character.
2. Caret position.
3. For future BiDi support - logical to visual mapping. I.e. - the next 
character logically is three characters down visually.

Please consider using it, so as my task (when I finally get to it, sigh) 
will be easier.
