I think that it is better to retrieve the value of the data at the pick
position:

    if picker.mapper is None:
        return
    cellid = int(picker.mapper.input.point_data.scalars[picker.point_id])
    col[cellid,3] = 50 

This works well if you don't have overlap between objects. It is a more
'canonical way' of getting the scalar value.

Sorry, I won't investigate further to see how the remaining flustuations
can be explained: it's too late, and I have do=too busy days.
