[mapserver-dev] LABEL FORCE GROUP - undocumented keyword

Hi Seth and all,

It is mentioned in the release notes for 6.2. 

"Inside a LABEL, a new FORCE GROUP parameter determines if the current 
label is allowed to intersect other labels from the same feature or not, 
and multiple STYLE blocks can be used to render graphic symbols instead 
of or alongside the text."

I remember using it when I did some nautical S52 signs a couple of years 
ago.  I would guess that the MET people also are using it to do their 
complex signs.

All the best,

/Lars Schylberg
