"""
This plugin opens a stack ROI window providing alternative views:

 - Usual sum of counts in the region
 - Channel/Energy at data Max in the region.
 - Channel/Energy at data Min in the region.
 - Map of the counts at the first channel of the region
 - Map of the counts at the middle cahnnel of the region
 - Map of the counts at the last channel of the region
 - Background counts

This window also provides a median filter tool, with a configurable filter
width, to get rid of outlier pixel.

The mask of this plot widget is synchronized with the master stack widget.
