Also converts HPGL line types to fixed (rather than adaptive). Varying
the pattern to fit each segment is going to look bad most of the time,
but particularly when stroking arcs or circles where HPGL will try to
repeat it for each chord segment.
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.
They are used for chamfered round rect pads, and can be used for custom shaped pads.
No actual change currently, but the shape rotation of custom pads and chamfered rr pads
can be now used in gerber plots.
This will later enable sorting the items for efficiency, which will then
facilitate things that would otherwise be impossibly slow (e.g.
switching pens)
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.
* 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.
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.
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
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.
