(I'm thinking about something like the lower-left QGIS guide window)

you could then "flip it" and make the display region drawn as say a blue
box inside the computational region. (computational region inside a
display region could be a red box). Maybe this is too nifty and asking
for confusion? Actually it would be ok if you could half-shade the
computational part in the guide-subwindow, so either a shaded box in the
middle or an unshaded box in the middle for the other mode. (visual-only
display area would be clear). A checkbox by the guide could turn that
effect on & off.

At some point we will have just reinvented the QGIS GUI..... maybe that
is best left to the QGIS/GRASS toolbox.

just to make things more complicated:
If display and computational regions are totally disconnected, you can
do other tricks in the display window like rotate the display along
heading instead of north-up.  (think of in-car GPS navigation displays)
