* Added a compilation selectable attribute -omtechstuff to ease debugging

  anti-overlapping algorithms. It is intended to report decision making data
  from the algorithm. It can be compiled by defining OM_TECH.

* Fixed a bad reported position in return from ZnQueryLabelPosition.
  Now the same algorithm is used by the widget for its internal use and
  for reporting purposes.
