Also includes a bunch of changes to simplifiy the terminology
and unify the copper, non-copper and keepout versions.
Also removes some legacy features:
Removes contol for fill method. If the fill method is currently
segments the dialog will ask if you want to convert to polygons
on OK.
Removes control of boundary resolution. We've done this with trig
since 5.0.
(cherry picked from commit 487aaeb)
Removes the need of using the legacy code in polygon/PolyLine.{h,cpp},
refactoring all CPolyLine instances with SHAPE_POLY_SET instances.
The remaining legacy methods have been ported to SHAPE_POLY_SET;
mainly: Chamfer, Fillet, {,Un}Hatch.
The iteration over the polygon vertices have been simplified using the
family of ITERATOR classes.
The zone creation in DRAWING_TOOL was a complex event loop whici
simultaneously managed the event handling, construction of the preview
polygon and the creation and commiting of the zone, all in the same
scope. This has been broken into several pieces:
* POLYGON_ITEM preview item, used to preview the polygon in progress
* POLYGON_GEOM_MANAGER is a class that collects points from user input
and used them to describe a polygon's geometry, including calculation
of 45-degree constrained leader lines
* ZONE_CREATE_HELPER is a class which deals with creating zones based on
geometry from a geometry manager and parameters from the DRAWING_TOOL
* The (much simpler) event loop in DRAWING_TOOL drives the
POLYGON_GEOM_MANAGER. With a minor refactor, this loop can be reused
in future for other polygonal tools if wanted.
The polygon preview now has a translucent fill which makes it easier to
visualise the zone.
This also adds the Close Zone Outline and Delete Last Corner actions as
part of the new event loop.
