Log:
Fix ticket: GETFEATUREINFO for line or points on MapGuide 2.2
http://trac.osgeo.org/mapguide/ticket/1858

When GetFeatureInfo for point or line geometry, simply using click point to query cannot get any matching. Expand selection geometry a little to be a linearRing so that can query point and line.
