.. instead of a Primitive2DContainer. The container very frequently contains only a single item, since the decomposition method often sticks only a single top-level node in there, so it turns out to be a net loss overall, memory consumption-wise. Also, if we return a single Primitive2DReference from a BufferedDecomposition, that maximises the sharing of data between the BufferedDecomposition objects at the bottom of the decomposed tree, and objects higher up.

|
|
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.
