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.
