plotters rework: add plot fct to use TEXT_ATTRIBUTES class to pass text settings

Old PLOTTER::Text is not (yet) removed, but it use negative text size
to mirrored text, which is not really compatible with some plotters (especially PDF).
Using TEXT_ATTRIBUTES is much easy and much better,
so PLOTTER::PlotText() is added.
Note: "old" PLOTTER::Text() is not removed yet.
