Anchors in Logic elements derived from Element2Term (e.g. Not) are tuples not Points

[Former user]

Anchors 'in', 'out' et c. are defined as tuples. This causes an exception if .anchor is called on such objects as Element2Term._place attempts to negate the coordinate point. Thus these anchors cannot be used ('start' and 'end' works as these are defined as Point).
