Hello,
I want to be able to rotate and flip the display of a GEF editor with a
ScrollingGraphicalViewer and ScalableFreeformRootEditPart, so only display
movement, no coordinate changes of Figures.
Could the following method work ?
subclass ScalableFreeformRootEditPart, with a subclassed FreeformViewport,
which uses a final user settable transformation in its translateXXX methods
or are there hidden caveats. I only need to display polygons, polylines and
ellipses.

The translate methods are not called when painting. Only when converting to
and from absolute coordinates.
