Pull changes to SVG.cpp to (#4144)
* Add lock/unlock using flock() for output gcode files. * Added description of unsupported_edges() from the cpp * Ported updates to SVG class from prusa3d/Slic3r. Thanks @bubnikv * Revert "Add lock/unlock using flock() for output gcode files." This reverts commit a0d42fe3dcda714a8ccc0230a113ed6f85159e6b.
