Follow-up Comment #27, bug #52193 (project octave):

I attached a "work in progress" version of both the patch for Octave and the
converter utility. Those address some of the comments that have been brought
by Dmitri and Rik:
* Polygon reconstruction is now implemented so that distant polygons won't be
accidentally merged (disabling anti-aliasing in Okular should not show
spurious lines anymore)
* SVG format is now also processed by the converter and one can inspect the
file in Inkscape

The remaining issues are:
* The converter has to be cleaned up to remove raster output code (unused in
Octave since we convert PDF to raster for better looking results) and
c++ify/cleanup the coding in general. I'll do that in a further step, if/when
the integration of this patch is accepted.
* 3D scenes are not much better after conversion. I think there is nothing we
can do about that with this approach.
* "pdfcrop" option goes through the ghostscript pipeline: I didn't handle this
because it may be useful to have the pdf processed by ghostscipt for
implementing the "tight" option
* Some misplaced characters in the PDF output: I have never faced this issue
and can't debug. @Dmitri: can you confirm that you still experience this
* Wrong bounding box: I have never faced this issue either. @Dmitri: can you
confirm that you still experience this issue?

The steps for building/patching/testing are the same as in comment #10.
