Graphic Primitives
==================
Graphic prmitives are the core of Gerbonara's rendering interface. Individual graphic objects such as a Gerber
:py:class:`.Region` as well as entire layers such as a :py:class:`.GerberFile` can be rendered into a list of graphic
primitives. This rendering step resolves aperture definitions, calculates out aperture macros, converts units into a
given target unit, and maps complex shapes to a small number of subclasses of :py:class:`.GraphicPrimitive`.
All graphic primitives have a :py:attr:`~.GraphicPrimitive.polarity_dark` attribute. Its meaning is identical with
:py:attr:`.GraphicObject.polarity_dark`.
