[GRASS-user] new wxGUI feature: Map Swipe

[Paulo van Breugel]

I am also just asking... contributing code is unfortunately way out of 
my league.

I am somewhat indifferent to whether synchronized display of multiple 
maps would be a general feature of map display or part of the swipe 
tool. I can imagine that it would be easier to make it initially part of 
a separate tool, but I am no developer so I could be completely wrong.

Cheers

Paulo
