p>Properties that require substantial computation are normally not processed
         until the script finishes executing. This is because setting one property could
         require the processing of other properties. For example, setting the <code>width</code> 
         property may require that the widths of the children or parent of the object also 
         be recalculated. And if the script recalculates the width of the object more than 
         once, these interdependent properties may also require
