Some years ago, I posted code to ensure that the aspect ratio of any new monitor 
would automatically match that of the existing region, and that the monitor 
would be of a sensible total size. I assume this is part of your motivation 
here? Those mods were done by hacking the XDRIVER/IRIS display drivers, but it 
occurs to me in retrospect that this could all be achieved with scripts. It 
would basically involve setting up an alias such that before any monitor was 
started, g.region would be run, the output would be parsed to extract ROWS and 
COLS, and then the MONITOR_WIDTH and MONITOR_HEIGHT environment vars would be 
set dynamically.

Now a question. Is the XDRIVER supposed to refresh itself after a manual 
re-size? It never used to on my system, and I never established how much of that 
was a local Xwindows configuration thing, and how much of it was an inherent 
Grass limitation.
