Problems with queries and toleranceunits

[Cameron Shorter]

Have investigated pixel problems further.  Not sure about other units.
It seems that that the point query is not acurate in selecting its
points.

See:
http://linuxdev.socialchange.net.au/webmap/museum/maps/demo_init.html
the mapfile is linked from there.
Try doing mutiple selections at various points on the map and you will
notice that in some places you will many responses where you'd only
expect one, and sometimes you will get none when you expect many.
