A use case for this could be the creation of graphics elements that needs precise control over positioning, like many Flash
applications/animations where the Graphic Team set the rules of what the application have to be, and sometimes they realize a prototype.
Another Use Case could be the Pivot GUI Builder, placing elements in GUI and moving them after, or set the desired layout after.
need to create pivot.wtk.Panel and pivot.wtk.skin.PanelSkin. I'd suggest that the skin always report a preferred size of 0x0
Suggestion for the names (AbsolutePanel ?) ...
