Allow the usage of System Design Language (sdl) shapes

There is a great set of sdl-shapes available that can be used in graphviz as External PostScript procedure. Would it be possible to make these available in the editor?

The shapes (shown below) were developed by Mark Rison of CSR and can be found in the contrib/sdlshapes directory within the graphviz package.

I'm not sure, but I don't think so. The editor is based on d3-graphviz which operates on SVG output only and from what I understand you have to use PostScript output for the SDL shapes.

Yes, using PostScript seems to be a requirement. Would you be able/willing to add them when I redraw them as svgs?

commented

I don't think Graphviz supports user defined shapes in any other format than PostScript so I don't think it's possible to do it that way.

Perhaps it's possible to use external images in some way through the image attribute. From what I can see it supports .ps files too. I'm uncertain however how the user interface should be in that case since the image attribute is part of the DOT source that the user supplies while I guess that the images themselves should be hosted by the editor application.
