align_set_geometry_ex

Superset of align_set_geometry that also builds SPIRALS. Each record is 8 doubles {type, x, y, bearing_deg, p0, p1, p2, p3}: type 0 = tangent (p0 = length; p3 != 0 -> bearing_deg is honored as an ABSOLUTE re-anchor for this tangent while the position still chains at the previous end — the polyline-sketch bearing break the AlignmentBuilder allows. p3 == 0 = chained bearing.) type 1 = arc (p0 = signed radius, p1 = length) type 2 = spiral (p0 = start radius, p1 = end radius, p2 = length; 0 = straight) type 3 = transition (p0/p1 = start/end radius as in the spiral, p2 = length, p3 = law: 0 Bloss, 1 cosine, 2 sine, 3 Helmert) type 4 = cubic parabola (p0 = signed end radius, p1 = PROJECTED length X along the start tangent; arc length is derived) Types 3/4 need a host with the v104 kernel; older hosts return 0 for the whole call (unknown record type), so probe by trying. x/y/bearing anchor the FIRST segment; later segments chain at the prev end.
