Real arcs (circular segments) in gerber export
Is there a reason why KiCad doesn't use real arcs in gerber export but makes an arc to be a bunch of small segments? Gerber format supports arc "draws" (identical to pcbnew arcs) and arcs as part of region outlines (pcbnew polygons and zones). Especially if KiCad "polygons" will support arc shapes in contours some day as in #4493, using arcs in gerber export would 1) make gerber files much smaller and 2) possibly be easier and faster to convert because it would be 1:1 with the gerber format.
