The oval clearance adds an edge on the 0-length side of a circular oval.
This is not needed and can affect the fill algorithm. Instead, we treat
round ovals as circles for pad polygons

(cherry picked from commit 57f0f88552)
This assumes maximum registration errors are a vector, rather than
an amount in both x and y axes. Lots more disucssion in the bug
report and on the forum (link in the bug report).
Also makes large changes to the painting of pads, but they now use
the same code as plotting, so if there are any changes then they
were errors before since plotting represents "truth".

Especially, small round rect pads have a ugly shape because the number of segments is
small and the 90 deg arcs are not very well approximated.
The minimal seg count for 90 deg arcs is now 4 (16 segm/circle) for pads.

This places the arc approximation setting in the kicad_pcb file and uses
it for all parts of the board rendering where arcs are converted to
segments. This allows the user to customize their speed vs. accuracy
tradeoff. The default setting of maximum error of 0.005mm is acceptable
for small boards on moderate systems.
This corrects an issue with fill segments-per-circle and moves the error
to segmetns calculation down in a number of functions to expose the
single value for approximation
This removes the remaining hard-coded segments counts and replaces them
with the relative error calculation where the segments per arc is
determined by the maximum error we allow (smaller arcs = fewer segments)
This is mainly the solder paste layer that shows this issue.
This is due to the fact SHAPE_POLY_SET::Inflate does not work fine with polygons with linked holes.
SHAPE_POLY_SET::InflateWithLinkedHoles it added to fix this issue.

For legacy boards, the setting is picked up from the board outline
thickness. If the board outline has mixed thicknesses, then the
max is used and a warning is displayed.

Allows 0 to 4 chamfered corners, not only one.
A custom shape allow this kind of shape. However because it is a primitive,
it is easier to edit and it support thermal reliefs.
Depending on thermal reliefs size, the polygons could be self intersecting,
and these self intersecting polygons are unexpected in zone calculations.
Other fix: the width of thermal stubs is clamped to the size of pads.
Previously, a bug in clamping calculations prevents constraining thermal stubs width.

The standard DIM() macro was not typesafe as it happily deferred errors
to runtime that can be caught at compile time. Replacing it with a
generic C++11 constexpr allows for typecasting, comparison and compile
time error checking.
Where we can get away with lower segment counts (localizing an anchor),
we keep the low-def 16 segment count. Intermediate values and values
that are visible to the user are set to high definition. Most are
simply hints to the inflation correction but where they show, the user
show see smooth lines.
Like circles, polygons are self-closed elements that define an outline.
This allows them to be used as such for board outlines and cutouts.

Rename GetPolyPoint() to BuildPolyPointsList(), because GetPolyPoint() looks like an accessor, but it is not an accessor.
(Using it as accessor can creates a *very long calculation time* for very basic access to polygon vertices)
