[GRASSLIST:5636] Linking Monitors script

[John Gillette]

try this:

Select and then Erase x1 and then display what ever you want there.
Select x0 and erase and display other info there.

Run this script to either pan or zoom in x0.  After finishing
the pan or zoom x1 will redraw it's contents at the same region
thereby "following" what ever is done in x0.

The disadvantage is that you can only do 1 pan or zoom at a time,
i.e. not interactively.

usage:

script_name z   <- does zoom instead of pan
script_name

zooming and panning in x0.  x0 is selected at exit.

Does this help?
