[GRASS5] [bug #4144] (grass) Gis.m display fails to update to new region changes with g.region

[Michael Barton]

As Maciek has replied, this is a 'feature' not a bug. Running g.region from
the command line or GUI will make a generic region setting. But in the new
GIS Manager, each map display has its own region setting (so each map
display can a different zoom).

So it's necessary to have a 'zoom to current region' button to zoom a
particular map display to the setting made by running g.region generically.
