I agree that better terminology would help a lot. I like "display region".
However, I'm not as sure about "computational region". The reason is that
computations and other GIS (non-display) functions can use the "display
region" OR the WIND file parameters, depending on the setting of a couple
environmental variables. What about "display region" for one concept and
"general region", "mapset region", or something else along that line for the
WIND file.
