Ian McInerney 13b6028e1b Refactor all math into a new kimath library
* Split up the thirdparty code into the thirdparty folder (#3637)
* Create a new kimath static library containing all the math functions

This is part of cleaning the build system for #1906.

Seth Hillbrand 9c8ae217a6 pcbnew: Treat circular ovals as circles
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

Jeff Young e1d5cf1a87 Change pad solder masks to use rounded-corner clearances.
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".

jean-pierre charras 8085899d0a Pcbnew: better approximation of arcs by polygons for pads having a very small size.
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.

Seth Hillbrand 37afcd93e2 pcbnew: Fix missing correction to Pad->Polygon transform
The rounded radius needs to be corrected even when there is no clearance
to ensure that the pad segments fall on the arc.

Seth Hillbrand 6bcf1839b7 pcbnew: Add arc approximation setting to board
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.

Seth Hillbrand ddc6079ceb Move remaining hard-coded segment counts
This removes the remaining hard-coded segments counts and replaces them

jean-pierre charras a155289f70 Custom pads: fix incorrect shape of masks when the shape is a polygon with holes and the mask margin is < 0.
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.

jean-pierre charras d259459a14 Pcbnew: add a new primitive pad shape: chamfered round rect pad.
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.

jean-pierre charras 200ff1cda6 Pcbnew: Fix incorrect polygonal shape of thermal reliefs of rect pads.
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.

Seth Hillbrand 1e5ba6f1b1 Replace DIM() macro
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.

Seth Hillbrand 25f8b1ce72 pcbnew: Update multiple zone segments
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.
