Tolerance is not working as expected

[murdav]

My question is linked to #5120.
Briefly I have some troubles with TOLERANCE and MAXSCALEDENOM for a point layer.

Part of the Mapfile:

If I use:

TOLERANCE 0
TOLERANCEUNITS pixels

queryByPoint never returns MS_SUCCESS.

If I use:

TOLERANCE 0.5
TOLERANCEUNITS pixels

I have more than 500 kilometers of tolerance (distance around the selected point) and queryByPoint returns always True.

If I use the default:

# TOLERANCE 0.5
# TOLERANCEUNITS pixels

I have more than 1000 kilometers of tolerance.

Any idea?

Closing without trying to re-produce. I am sure that tolerance works as expected for some users with maxscaledenom. Refresh the ticket with a re-producible test case for MS 7.x or 8.x if needed.
