<DL>
<DD>Determines how attractive a break opportunity in 
 this view is.  This can be used for determining which
 view is the most attractive to call <code>breakView</code>
 on in the process of formatting.  The
 higher the weight, the more attractive the break.  A
 value equal to or lower than <code>View.BadBreakWeight</code>
 should not be considered for a break.  A value greater
 than or equal to <code>View.ForcedBreakWeight</code> should
 be broken.
 <p>
 This is implemented to forward to the superclass for 
 the Y_AXIS.  Along the X_AXIS the following values
 may be returned.
 <dl>
 <dt><b>View.ExcellentBreakWeight</b>
 <dd>if there is whitespace proceeding the desired break 
   location.  
 <dt><b>View.BadBreakWeight</b>
 <dd>if the desired break location results in a break
   location of the starting offset.
 <dt><b>View.GoodBreakWeight</b>
 <dd>if the other conditions don't occur.
 </dl>
 This will normally result in the behavior of breaking
 on a whitespace location if one can be found, otherwise
 breaking between characters.<DD><DL>

<DD>Breaks this view on the given axis at the given length.

<DL>
<DD>Creates a view that represents a portion of the element.
 This is potentially useful during formatting operations
 for taking measurements of fragments of the view.  If 
 the view doesn't support fragmenting (the default), it

 This view does support fragmenting.  It is implemented
 to return a nested class that shares state in this view 
 representing only a portion of the view.<DD><DL>
