the paragraph has a wrap method which effectively breaks the lines using a 
specified width and height. So

P.wrap(availWidth,availheight)

returns the required width and height determined from the way the paragraph 
splits. Unfortunately for performance reasons the broken lines are stored in a 
fairly complex way in P.blPara.lines. So the height of the paragraph is 
len(P.blPara.lines)*P.style.leading.
