v.mkgrid: lines not areas

[hamish]

Hi,

Nice to see the new -p points mode for v.mkgrid to save the v.extract centroids + v.type step.

It would also be nice to have a -l flag to create the grid as lines to save the v.extract boundary + v.type step. These are nice to create in a wgs84 lat/lon location and then v.proj into a projected location. 'd.grid -w' does this, but it's nice e.g. for a shapefile you can use as an overlay in QGIS.

or get rid of the flags and have a type=area,points,lines option.

thanks, Hamish

(v.category step also needed)

also all segments of those grid lines should share a common cat, and that cat be linked to attribute columns ??_str and ??_dbl with nicely formatted & raw ordinate value.

The option to generate lines instead of areas (new -l flag) would be highly welcome.

Please check and try r61519.

If it works should be backported?
