[Chameleon] querybyshape() in layerobj and in mapobj

[Julien-Samuel Lacroix]

Hi,

In your mapfile, all queryable layers can have a TOLERANCE set which 
correspond to the sensitivity of the search in pixel. For polygons the 
default TOLERANCE is 0. This mean that the shape returned must be within 
the shape. If you set a tolerance of 1 or more this may solve your 
problem. See the documentation:
