* \brief A piece of text to be drawn on a Plot.
46
* Contrary to its name, Legend is not just used for the plot legend,
47
* but for any kind of text; particularly also for the "Add Text" tool.
48
* Accordingly, it is also referred to as "TextMarker" by other classes.
50
* \section future_plans Future Plans
51
* Rename to TextMarker (or maybe TextEnrichment; see documentation of ImageMarker for details).
