This functionality is necessary to be able to display a cropped version of the original manuscript page, showing a particular letter instance and an arbitrarily sized contextual margin around it, when the cropped/binarized version of the letter instance is clicked or moused over in the scriptchart.
This implementation is based on @versae's utility scripts for excerpting letter instances for display in the admin interface. It's a bit experimental and probably could be made more efficient, but it works OK.
