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.

Rather than skipping our endEdit() call in libedit, we need to
parameterize whether we want the shape open/closed. Closed will remove
the last segment if it lands on the first point. We don't want that
but we do want to remove the last point if it duplicates the second to
last (in the case of double-clicking)

(cherry picked from commit 55020c2b89)
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.
