Hi David,

Several formats do appear to record this information, but in my experience
it's often challenging to locate and decode: it's a small amount of
coordinate data in an unknown coordinate system, and in some formats it
might be commingled with other metadata in an unlabeled binary blob.

OpenSlide doesn't currently expose this information, but could do so if
someone wants to work on it.  I've filed an issue for future reference:

This is often easier, but OpenSlide doesn't currently expose it either.
