What about cases like Markus's PHP earthquake map, where you want the
new big symbols to be drawn on top of older ones? If automatically
sorted, there is no way to unsort them in cases when that is more
appropriate.

work-around 1) fillcolor = none

work-around 2) border color = none. Then all are equal depth :)

work-around 3) things are drawn by their cat #, so add a column,
populate it with a ranking, and then use v.reclass column= to use them
as cat numbers.


Support for GRASSRGB in ps.map is wish #3299.
