[OpenSCAD] DXF for cut and engrave

The  essential problem is that there is currently no work flow for laser
cutters that allows you to use the output from openscad directly,
essentially there is no slicer. In an ideal world, you would be able to use
openscad to produce 3d shapes representing the material cut away by the
laser, and the 'slicer' program would calculate the required beam paths and
intensity levels, but as the that doesn't exist yet, it's not a very useful
approach to take. For better or worse, laser cutter designs currently
consist of 2d open or closed paths, generally with colour used as a hint
for beam intensity. If openscad was able to produce output like this, it
would be immensely useful to a LOT of people almost immediately.
It also seems like far less work to modify openscad to support output like
this, than it would be to both create a slicer program for laser cutters
AND change the work flow of all of the people using laser cutters
