[OpenSCAD] DXF for cut and engrave

The main issue with OpenSCAD in regards to laser cutting / engraving is
that "Solid Modeling" does not transfer well to "line art".  There's no
practical way to define a standalone "hairline" with no width.  It works ok
If the line you want corresponds to the outline of a soiid, but the
"standalone" qualifier is the problem.   You can approximate lines with
thin rectangles, but the laser will end up doing a double pass along the
two long sides no matter what.  The other issue is that lines can't really
be made to overlap.

I'm not sure if its even feasible for OpenSCAD to support such features,
since its such a fundamentally different usage from solid modelling.
