[mapserver-users] How to avoid drawing overlapping point symbols?

[Sigda, Mark - Fort Collins, CO]

I have a point layer I'm drawing with a truetype symbol.  When points are close together, a big mess of overlapping symbols is drawn.  

How can I tell MapServer not do draw symbols for points that are close together?  I'm looking for something like GAP on the STYLE element, but that apparently applies only to line features.

Thanks,
