 * Use Polygon Approximation: Uses an approximation to find hidden lines. This is fast, but the result is a collection of short straight lines.
 * Show Hard Lines: Shows hard and outline edges (visible lines always shown)
 * Show Smooth Lines: Shows smooth lines. A smooth line is a line indicating a change between tangent surfaces, as in the transition from a flat surface to a fillet.
 * Show Seam Lines: Show seam lines. A seam line is a boundary between faces.
 * Show UV ISO Lines: Shows ISO lines. ISO stands for isoparametric. Here is a description what isoparametric lines (in fact curves) are.
 * ISO Count: The number of ISO lines per face edge.
