Hi Alexandre,

Thanx for the pointer.  I tested on the GP InitialView example 
(http://localhost:8081/gp/samples/initialview/index.php?workspace=wms2&id=302) 
and what I thought would apply only to polygons ends up applying to 
points as well.  As it turns out, geometry.point has a getCentroid 
function.  geometry.polygon does not, but it inherits from linearRing 
and that has a getCentroid.  I haven't tested with a geometry.linestring 
but I went up the dependeny stack and geometry.collection implements a 
getCentroid, so my guess is that it works for lines too.  I'll commit 
what I have now.  I'll add a linestring example later.

Thanx (and sorry for the late answer!),

Yves
