Yes, you're probably right even though this involves computational regions
rather than display regions. I've already thought of this, but wanted to get
the whole concept working before I tackled the tricky problem of trying to
code one of these approaches (tricky because of different formats between
latlon and non-latlon regions).

Do you have a recommendation for which would be better in this case? I
assume that in either case, I'll have to replicate the entire region
information even though I only need to temporarily change the resolution
while r.out.ppm is running.
