Comment 6 for bug 1753224

Interesting.

@Tomasz, the cause of this is bumping up the number of segments in an arc. It used to always be 16 or 32 (because we mostly use them for zone corners, pad outlines, and other small features). But large arcs (drawn by the user on silk layers) plot poorly to gerber in outline mode because they still only have 16 or 32 segments.

Can we optimise zone filling to deal with a higher-segmented board outline, or do we need to figure out a way to make the patch gerber-plotting-specific?
