vtkHardwareSelector selection bug with coincident points from different actors
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When selecting coincident points from different objects, the hardware selector selection result only gives the point IDs of the last renderered actor.
This results in incorrect selection behavior for the first rendered one.
To reproduce the bug, create two adjacent polydata which are in contact (i.e., they have points which share the same coordinates) and try to select points in the contact area.
