Comment(by vesnikos):

 Hey Hamish,

 Yeah, I know about that module but im not sure if you can specify the
 region.

 Usually I identify visually a spot in my raster where a certain algorithm
 needs to be run. mostly holes that need to be filled with r.fillnulls. So
 I don't need it for the hole raster. Just for that spot. So preserving the
 raster's resolution makes sense. Plus its trivial to change it the res
 flag of 'g.region'.

 If you have to do that more than three times, its too time consuming to
 querry the edges, and then plug them in g.region

 What I had in mind is more like a functionality like the 'zoomIn' button,
 but instead of zooming in, it should change the computational extents of
 the rectangle you draw.
