[news.eclipse.tools.gef] FigureCanvas vs. ScrollPane: a question

["Mark Powell" <Mark.Powell@xxxxxxxxxxxx>]

So, in the Draw2D API there are these two classes that can contain Figures 
and provide scrolling: FigureCanvas, and ScrollPane.
FigureCanvas is lightweight (the O/S provides the scrollbars), and 
ScrollPane is heavyweight (Draw2D paints the scrollbars).

Is the choice of which of these widgets to use purely aesthetic?

Are there any features other than how the scrollbars are rendered that you 
get with using one versus using the other?

For instance, are each of these classes taking equal advantage of clipping 
to the viewable area during repaints via DeferredUpdateManager, or is one of 
these classes "smarter" about clipping than the other?

Thanks,
Mark
