Potential SVG format issue (convert SVG to PNG)

[TerryHoCQ]

This is an amazing project, thanks for your nice work. I found it's very hard to convert SVG to PNG by some tools (rsvg-convert). And it's incorrectly shown in Inkscape. Hope you can check this issue, thanks!

Sorry for the extremely delayed response! If you could attach some examples of the problem (the SVG in question, and the incorrect displays from Inkscape/rsvg-convert) I can take a look.
