GraphicalViewerImpl
A Graphical Viewer implementation which uses a
FigureCanvas
for native scrolling. Because the scrolling is handled natively, the root editpart
should not contain a
ScrollPane figure. Do not use root
editparts which provide scrollpane figures, such as GraphicalRootEditPart.
The RootEditPart for a ScrollingGraphicalViewer may contain a Viewport. If it does,
that viewport will be set as the FigureCanvas' viewport. FigureCanvas has certain
requirements on the viewport figure, see
FigureCanvas.setViewport(Viewport).
