These aperture macros were previously used but only for chamfered round rect.
They are now also used for custom pads (previously drawn as regions).
They are also optimized, i.e. only one aperture macro is created for a given shape.
(previously, one aperture macro was created for each chamfered round rect pad.)
So now all pads are flashed.
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.
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.
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.
