Hi,

I am interested to hear more about the library limitations.. you
mean the WIND region, right? I'd be surprised if WIND_OVERRIDE or
GRASS_REGION enviro variables (and the python wrappers for them)
didn't provide full control for whatever someone might like to do.

I would guess if the scatter tool was spawned as an independent
process, it could maintain its own environment & so it's own region
override enviro variables. or simply unset the wxGUI display overrides
and just use the mapset's real computational region read directly from
the WIND file?
