[GRASS-dev] single-click zoom doesn't preserve aspect ratio

[Maciej Sieczka]

Michael,

Now that the gis.m - WIND interaction is OK, I would like to raise the
remaining issue with zooming in gis.m:

The single-click zoom in/out doesn't preserve the aspect ratio, in the
constrained zoom mode; it expands the region to fill the whole map
display canvas instead, like if it was the "Map fills display window" mode.

Maciek

P.S.

Trying to switch to "Map fills display window" mode, I get an error:
