I've been using IDLanROI and IDLgrROI for a while and each time I use
them I come to a different conclusion as to how they actually work. I
seem to always get slightly offset masks from ComputeMask when I
compare the mask and verticies on object graphics.

I've written a small article and program to demonstrate the problem.
