Using nwres and ewres set to 3 also made no difference.

Setting the region to the DEM allows r.flow to run, but it does not produce
the flowline map, only flowlengths and flowaccumulation.

So, three (perhaps related?) issues remain: 1) no display of raster maps
regardless of region, 2) r.flow does not produce flowline map, and 3) cannot
set nsres/ewres to integer 3 on vector analytical_area map.
