    stroker: Avoid emitting a miter join for across an elided degenerate
segment

    Given the criteria of the rectlinear stroker that it only handles
    horizontal and vertical line segments, and eliminates degenerate
    segments before stroking, we must be careful not to apply a join between
    two horizontal segments (for example if the intervening vertical segment
    was degenerate and so elided). A miter join between two colinear
    segments is empty, yet we were blissfully extending the line caps to
    cover the join.

    Fixes: outline-tolerance
