/**
* @brief A single base class (PCB_TRACK) represents both tracks and vias, with subclasses
* for curved tracks (PCB_ARC) and vias (PCB_VIA). All told there are three KICAD_Ts:
* PCB_TRACK_T, PCB_ARC_T, and PCB_VIA_T.
*
* For vias there is a further VIATYPE which indicates THROUGH, BLIND_BURIED, or MICROVIA,
* which are supported by the synthetic KICAD_Ts PCB_LOCATE_STDVIA_T, PCB_LOCATE_BBVIA_T, and
* PCB_LOCATE_UVIA_T.
