buffer (GEOS) in Mapserver 4.6

[Yewondwossen Assefa]

Hi There,

  The php does not yet expose those functions. There is a bug opened on 
that but It is still not adressed for now. Although I do not have a 
precise timeline, It should be done in the coming weeks. 
(http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1327).
