Update hidden line generation for DXF output and Make2D - don't refit rationals (like circles and ellipses) as cubics for DXF or Make2D output since unlike AI/PDF format these can handle full rational bspline output. Accuracy of the generated result is greatly improved. Since it can use only local operations slowdown is only about 4%. Improve accuracy of hidden line results by performing curve/curve intersections when visibility changes, to align the transition point accurately to other geometry. Lots of tuneups for hidden line generation:
