+            This is a helper primitive to hold evtl. WrongSpell visualisations
+            in the sequence of primitives. The primitive holds this information
+            separated from the TextPortions to where it belongs to, to expand the
+            TextSimplePortionPrimitive2D more as needed.
+
+            A renderer who does not want to visualize this (if contained at all)
+            can detect and ignore this primitive. If its decomposition is used,
+            it will be visualized as red wavelines.
+
+            The geometric definition defines a line on the X-Axis (no Y-coordinates)
+            which will when transformed by Transformation, create the coordinate data.
