Hi guys,
This request is based on a talk with Sameboat
Wikimedia Commons uses LibRSVG for rendering SVG into PNG on-site which is quite different from most browsers and Inkscape, but RSVG has so many flaws and bugs, the ones that directly affect my diagram are: lack of text on curved path; texts render poorly when it is rotated or scaled, text would appear bumpy; lack of desired typefaces on-site which matters aesthetically.
Unless Wikimedia can arrange an expert to take over RSVG from GNOME (obviously a pipe dream), all the reported flaws and bugs would unlikely get fixed in the near future.1 2
Thanks
