Prevent drift between ROI coordinates and where Open Seadragon renders the overlay #108

@pletcher: I created a CodePen that reproduces the issue you were seeing within Beyond Translation / the Scaife Viewer frontend:

This differs from the same coordinates being passed directly to the IIIF server:

I'll keep digging into Open Seadragon to see if I can figure out what is going on.

@pletcher: I've got a lead on this...will loop back soon.

@pletcher: Please check out the updated CodePen; I've left some comments on why we were seeing the drift. Feel free to adapt this into your work within scaife-viewer/frontend:
