When collecting a glyph's segments, we can't simply call the glyphs' draw method with the GetSegmentsPen, but we must initialize the PointToSegmentPen explicitly with outputImpliedClosingLine=True. By default PointToSegmentPen does not outputImpliedClosingLine -- unless last and first point on closed contour are duplicated. Because we are converting multiple glyphs at the same time, we want to make sure the _get_segments function returns the same number of segments, whether or not the last and first point overlap.
