Created by jkrei0 here https://github.com/jkrei0/solvespace Optimized for size. Merged all but `shaded.png` since in my opinion the current one is better. Discussion here https://github.com/solvespace/solvespace/issues/857
The states are: * Draw all lines (on top of shaded mesh). * Draw occluded (by shaded mesh) lines as stippled. * Do not draw occluded (by shaded mesh) lines. As usual, the export output follows the screen output.
