[UMN_MAPSERVER-USERS] Limit of 1 label per polygon

[Léveillé, James]

Hi Stephen,

I didn't mean I actually had performance issues.
I just THOUGHT that the few calculations made by MapServer to check if more
than one label had to be placed in each polygon would be slower than
systematically placing only one label (less calculation). This is the reason
why I was asking.

Thanks.

MINDISTANCE is exactly the tag you need for this, that is why it is 
here. If you have a performance problem than tell us about that. What 
makes you think MINDISTANCE would be slower than any other tag.
