May I request the infrastructure to implement a slight embellishment on
Many of us use online virtual-slides for testing medical students.
It would be useful to have a mechanism to "shift" the locations in both
X and Y by moving the origin.
If we randomly changed the origin on the Slide-Server with each session,
no student could cache that information for the next examinee.
Hope this makes sense.
