Add shapeObj.DouglasPeuckerSimplifier() in MapScript?

[Steve Lime]

The API (that I knew about) is already exposed via mapscript. That
generalization function
is new to me. Easy enough to add to mapgeos.c and then mapscript.

Exposing it as a layer processing option is another matter and is a
good fit for
Tamas data adapter RFC. Note that I translated the Peucker algorithm
from ESRI Avenue
to MapScript (in perl) years ago (see
http://mapserver.gis.umn.edu/community/scripts).

I think that exposing GEOS api via mapscript makes sense. A big part of

working with mapserver is being able to prep the data that you will 
ultimately serve. I think mapscript is a great way to do this. People 
that are already working with mapserver/mapscript could use it to do a

variety of tasks in this area without having to download and learn
other 
tools. I do not think exposing these apis in mapscript should impose a

lot of additional baggage on mapserver other than documenting them.

The other option might be to look at adding it to ogr or looking at a 
separate project to focused on building an opensource variant of 
something like fme, which is probably outside the scope of your 
immediate needs, but might be an interesting project none the less.
