 Recently I discovered that `g.region vector` does not work with vectors
 with no topology (level 1). I fixed this issue similarly as `v.info` do
 (level1.c) in r70302. Then I found similar issue when trying to colorize
 points based on z-coord (`d.vect zcolor=elevation`). It uses
 Vect_map_get_box() source:grass/trunk/display/d.vect/shape.c#L180 which
 requires topology (1).

 My suggestion would be to modify Vect_get_map_box() to work also on level
 1 (fill bbox by reading features). I am not sure about consequences, any
 opinion?
