TAlignmentPatternFinder.handlePossibleCenter Method
Definition
This is called when a horizontal scan finds a possible alignment pattern. It will cross check with a vertical scan, and if successful, will see if this pattern had been found on a previous horizontal scan. If so, we consider it confirmed and conclude we have found the alignment pattern.
