add a layer selector to r.region

[timmie]

r.region has the option to adapt the region boundaries to raster or vector layers in the "option" tag.

Currently, users are forced to enter the layer name manually.

Please add a drop-down box here.

+  parm.raster->gisprompt = "old,cell,raster";

should do it. but better would to use G_standard_option()s for map,raster,align and vector map options. and perhaps region and 3dview too?

Replying to hamish:

Done in r40902.

and perhaps region and 3dview too?

There aren't standard options for these, but I've added ->gisprompt settings for them (copied from g.region).

Backported to 6.5 and 6.4. Closing (feel free to reopen if needed).
