See what ZZMbox does: it does exactly what you want to do here.
The magic is that if there's a period in the name, it looks at it as
Module.rastername (well, ZObname now - a lot changed in the past few
hours.)

Are you sure this wouldn't be easier to do by creating two wholly new
views whose cursors are locked using cursor-cargo?

If not, then it may be time for cursor magic: a dimension on the cursing
cell which indicates routines to run when he cursor is changed. This would
be started by ZZCursorReal, which then must be made the only way in which
cursors are moved.

The former is cleaner but slightly more difficult on the rasters,
possibly, and the latter is less clean but much more powerful.
