The p.wrap should specify a very large number for the second argument just in 
case we change the paragraph algorithm to give up early. so

p.wrap(vailwidth, availheight) --> (required width,required height)

returned value is (required width, required height) so your paragraph required 
at least 372 points in height. Normally the returned width is the same as the 
available width which you pass in.
