Comment(by mphaneuf):

 Maybe the following function MgGeometry*
 MgHttpWmsGetFeatureInfo::GetSelectionGeometry(MgMap* map) in
 /trunk/MgDev/Web/src/HttpHandler/HttpWmsGetFeatureInfo.cpp should be
 modified to take a small buffer into account.

 The calculation for the geometry is done using a single pixel. Including
 rounding errors, it is highly unlikely that this would work using a single
 point. Perhaps a buffer done by adding N pixels around the pixel and then
 creating a polygon, instead of a point. It would fix the issue.
