[GRASS-dev] gis.m zooming: 2 new bugs

[Maciej Sieczka]

Micheal,

With your today commited fixes for gis.m the single-click zoom-OUT bug
seems gone, which is cooler than ice-cold.

But, a new beast cropped out in regard to single-click zoom-IN for a
change.

Based on spearfish60.

1
add "slope" raster, 'Zoom to selected map'

2
zoom-in by selecting a region with mouse - make the region higher than
wider

3
zoom-in by single-clicking - whole canvas is filled - the aspect ratio
is not preserved when zooming! single-click zoom-OUT *does* preserve
aspect ratio...



Another bug is that zoom-out by selecting a region with mouse leads to
unexpected results, like if only the Y coord was handled correctly.
Reminds of the now-fixed single-click zoom-out bug. Proceed the same
way I described that, to spot this one too.



Good luck in fixing these.

Best,
Maciek
