Minfeaturesize??

[Steve Lime]

Note that you can use the sortshp utility in MapServer to order
features
by size assuming you have an attribute that stores area. This is a bit
more
high performance than the MINFEATURESIZE approach since not all
features
need be processed. I do like the idea though and would like to get in
place
by the 4.6 release...

Ok, I have opened an enhancement request to add this to mapserver.
