Setting a line thickness = 0 for graphic objects (circle, rect, line) is
allowed but creates issues for circles that were plotted a non filled shapes
but having a outline thickness = 0.
To avoid issues with broken Gerber readers use aperture macros with shapes
without rotation when more than one primitive is required.
In many gerber readers, rotation of a set of primitives is broken
(do not follow Gerber requirements)
plotter.h contains now only a header common to all plotters.
The code does not actually change, but it allows modifying a specific plotter
without recompiling most of kicad files.
1) For a while now we've been using a calculated seg count from a given
maxError, and a correction factor to push the radius out so that all
the error is outside the arc/circle. However, the second calculation
(which pre-dates the first) is pretty much just the inverse of the first
(and yields nothing more than maxError back). This is particularly
sub-optimal given the cost of trig functions.
2) There are a lot of old optimizations to reduce segcounts in certain
situations, someting that our error-based calculation compensates for
anyway. (Smaller radii need fewer segments to meet the maxError
condition.) But perhaps more importantly we now surface maxError in the
UI and we don't really want to call it "Max deviation except when it's
not".
3) We were also clamping the segCount twice: once in the calculation
routine and once in most of it's callers. Furthermore, the caller
clamping was inconsistent (both in being done and in the clamping
value). We now clamp only in the calculation routine.
4) There's no reason to use the correction factors in the 3Dviewer;
it's just a visualization and whether the polygonization error is
inside or outside the shape isn't really material.
5) The arc-correction-disabling stuff (used for solder mask layer) was
somewhat fragile in that it depended on the caller to turn it back on
afterwards. It's now only exposed as a RAII object which automatically
cleans up when it goes out of scope.
6) There were also bugs in a couple of the polygonization routines where
we'd accumulate round-off error in adding up the segments and end up with
an overly long last segment (which of course would voilate the error
max). This was the cause of the linked bug and also some issues with vias
that we had fudged in the past with extra clearance.

We output a 0 opacity text in the SVG plotter to allow searching. When
this text is changed to 100 opacity, it can show up on the user screen
and so needs to be mirrored to match the stroke font output

Add missing plot and print changes for the new bus entry properties.
ADDED: Junction properties diameter and color can now be edited.

Due to rounding issues, sometimes (especially for rotated pads) the region
(4 segments+4 arcs) was incorrectly closed (1 unit (nanometer) mismatch between
start point and end point.
Although it does not create bad shape, its breaks the round rect pad identification
in CAM tools.
start point and end point are now the same.
These pads were plotted as a segment. This is not the right way.
Pads must be flashed or plotted as regions, not painted.
They are now plotted as Gerber regions round rectangle pads.
These regions are similar to flashed pads.
Previously, the region was a usual polygon with arc approximated by segment.
Using a region with arcs is a better way because it allows CAM tools to
identify this region as a round-rect pad.
A side effect is a better shape and smaller files, however not really noticeable in fact.
Previously, for historical reasons, they were added only if
Include Netlist Attributes option was on.
But Aperture Attributes have nothing to do with Netlist Attributes, and good
Gerber files must include them.
Some buggy SVG interpreters can't handle 0-length ovals. In this case,
they are meant to be circles, so we can export as circles in our
plotter.

* 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.
They are now in a specific block and no longer combined with an other command.
(combining these commands with an other command (D01 or D02) is deprecated)

This is the first step to allowing non-segments in the line chain.
External routines cannot be allowed to change the line chain without
going through the internal routines. To accomplish this, we remove the
Vertex() and Point() access routines and only leave the const versions.
Transformations are given for both points as well as the chain itself.
Standard apertures are circle, rect, oblong and polygon (regular polygonal shapes with 3 to 12 vertices)
The support of the standard aperture type polygon was missing in Gerber plotter.
When plotting in Eeschema, various elements may be filled with either
the foreground or background colors. The fill mode is rather unique,
requiring un-stroked pie wedges for arcs and both closed and open filled
polylines.

This handles images with transparent colors by mapping the transparent
color to white. This only works when plotted into the background.

* rename WS_DRAW_ITEM_POLYGON to WS_DRAW_ITEM_POLYPOLYGONS (better name)
* use SHAPE_POLY_SET instead of std::vector(<wxPoint> to manage the set of polygons.
It also remove duplicate code related to HitTest and bounding box.
* fix HitTest and WS_DRAW_ITEM_POLYGON highlight.
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
Note that the comment in line 142 where the scale factor was set had the
correct value to indicate metric (1) but in the actual boilerplate, we
set imperial (0). This has been around for 6-8 years, so it would seem
DXF is not our most popular export.
Note, I initially tried to use '1' to specify metric units but this was
not handled by DXF readers (QCAM, Inkscape). Instead, scaling the page
units to inches properly seems to work.
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.
This was previously "svg:g", but the SVG is declared with only
a "default" namespace, not an "svg:" namespace (looks like
xmlns:svg="http://www.w3.org/2000/svg" in the svg tag).
This means you cannot use svg: as a NS in the document. It's not
needed anywaY: the default is already correct.
Moreover, mismatching <svg:g> and </g> is always invalid.
Uses existing grouping in SVG output. Sets schematic components as a
grouped element in SVG as well as pcbnew elements per layer.
