[MAPSERVER-USERS] Displaying population density with Mapserver

[Pierre-Benoit Besse]

Yes, but I need them to adapt for different extents.

For example, When I zoom out enough to see the world, I need them 1 pixel
wide (it's ugly otherwise), but when I zoom in I will need then 2 or 5 or
even 30 pixels wide to cover all space.
