from 5 degrees to calculated based on ARC_HIGH_DEF.

(cherry picked from commit b8a7a66a0a)
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.
They don't define a KiCad string class, so the header file name was
somewhat misleading. But the fact that they didn't match definitely
made coding more difficult.
The move tool can stack on others, so when we re-enter the previous tool
this caused another immediate action. We flag re-entry in the tool
stack to check for this and avoid unexpected tool starts
