Is there a facility within ImageJ to automatically draw the major axis on
the ellipse that bounds an ROI?

If the image has been thresholded and ROI selected, the "measure" tool
will calculate the major and minor axis of the bounding ellipse, so it
must be possible to combine this with the draw function. I am however not
well versed enough to do it myself!

I want to do this to compare line profile plots of the same cell over
images taken at different times, and a manual draw is prone to error.
