Comment 13 for bug 400592

@hefee - ATM it's 'just' that you are working on it (Status 'In progress'), the importance 'Wishlist' means that its an RFE for Inkscape (to be added in the future). OTOH if you no longer want to develop or maintain it, you can change the assignment back to 'Nobody' and hope that someone else will pick it up from there ;-)
Whether it will be added to the extensions that are bundled with Inkscape needs further discussion here (or maybe in the inkscape-devel list) I assume. It could be helpful to add a more detailed description or SVG file that demonstrates several use cases (e.g. similar to the "Summary of capabilities (SVG)" for the recently filed 'Wireframe spheres' extension in bug #461964 <http://launchpadlibrarian.net/34456048/Wireframe%20sphere%20tutorial.svg>).
