This method is mainly for use in implementing the
* updateDisplayList()
method, which is where
* you compute this object's actual size based on
* its explicit size, parent-relative (percent) size,
* and measured size.
* You then apply this actual size to the object
* by calling setActualSize()
.
In other situations, you should be setting properties
* such as width
, height
,
* percentWidth
, or percentHeight
* rather than calling this method.
