DescriptionIssue 680: clusters collapse when applied to repeated chords
This replaces the rather shaky calculation of rounded polygon
outlines (unchanged since 2002AD) with something grounded somewhat
firmer in vector algebra. As a result, the rather flowery
interpretation of clusters so far (previously confused by concave
corners and other things) is becoming a lot more boring.
Implement inline Real cross_product (Offset, Offset)
Patch Set 1 #Patch Set 2 : Fix winding area sign, simplify flag drawing, tweak cutoff angle #Patch Set 3 : Remove Lookup::rotated_box's bug compensation of Lookup::round_filled_polygon #
