title: Adjusting the height of Unity 4.6 UI Text according to content
body: <p>I am new to the unity's latest UI. What I know about UI Text Element is, we can wrap the text with in the horizontal bounds, but if it comes to next line, either it overflows or it truncates. If it fits in the height, font size decreases. What I want is to adjust the height of the text area according to the content it contains, without affecting the font size inside.</p>
  
  <p>I will be having many text elements as childs to a parent panel, the panel itself will be child to a scrollable container. So I have to calculate height of all the children to adjust the height of the parent panel.</p>
  
  <p>How do I achieve it?</p>
