Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
Eeschema shows background fills on a different z-level than the rest of
the symbols/elements. Print the backgrounds prior to the foregrounds in
order to preserve this view for print output
Fixes https://gitlab.com/kicad/code/kicad/issues/12559
This also fixes a failure to use the correct effective width for
shapes (which might, for instance, inherit their widths from schematic
defaults, netclasses, etc.).
Fixes https://gitlab.com/kicad/code/kicad/issues/11358
Also fixes some plot bugs with arcs.
Also moves polygonization of arcs (when required) in plotting code
from 5 degrees to calculated based on ARC_HIGH_DEF.
Fixes https://gitlab.com/kicad/code/kicad/issues/5017
ADDED arc, circle and rectangle shapes for schematic. Shapes support
line styles and fill colors.
CHANGED sheet background color in Edit Text & Graphics Properties to
fill color (and it now affects shapes).
Pushed STROKE_PARAMS down into common and moved all shapes to using it
for stroke descriptions.
