DXF export confuses `dxf2gcode`
I don't know if this is an Inkscape bug, or a dfx2gcode bug.
The situation is that a simple drawing containing 64 plain circles, saved as DXF and imported into dxf2gcode causes an excessive amount of CPU spin on loading into the latter, and eventually complains about having many very short segments.
I originally reported this as a bug against dxf2gcode:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=895865
but the files were analysed and found to contain lots of very short elements. It was suggested to be a bug in "the exporter" - namely Inkscape.
I then reported this on Inkscape itself:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=908541 https://bugs.launchpad.net/inkscape/+bug/1793530
who analysed the files and found they don't contain many thousands of items, just a few splines. They also suggested to move the bug here as it's more of an issue for an extension, than core Inkscape itself.
So here I am - I don't know quite whose bug this is, but either way I feel that I'm not asking {Inkscape + dxf2gcode} for anything very complicated, so between them they ought to cope fine with my request.
