I can't change that, because it is the behaviour of the widget in QT. It 
counts paragraphs, not line. I kept the word line, and I agree it becomes 
strange when Wrap is True.

At the moment, you must do it by hand with Font.TextWidth. I think I will make 
a function HeightForWidth that will return a text height when the width is 
given.
