Sorry to bother you again.

Editing placed points in SurfaceCut generates this error :

> Traceback (most recent call last):  
> File “/home/user/bin/Slicer\_Ext/SlicerSegmentEditorExtraEffects/SegmentEditorSurfaceCut/SegmentEditorSurfaceCutLib/SegmentEditorEffect.py”, line 257, in onEdit  
> self.logic.setPointsFromString(self, self.segmentMarkupNode, fPosStr)  
> TypeError: setPointsFromString() takes 3 positional arguments but 4 were given

Using SlicerSegmentEditorExtraEffects at 9933c4c2175.
