Detailed Description

All regions are specified in "linear coordinates", not "pixel coordinates".

This is necessary because "linear coordinates" scale with zooming whereas "pixel coordinates" do not. Unfortunately, this means that coordinate transformation is required each time the region is drawn.

Ellipse is derived from Rectangle, but we have no way to generate ellipse statistics for a measurement set (our only non-image display data)...

so we have to define this to prevent MS info being reported for the bounding rectangle of an Ellipse...
