Re: SVG to PNG

 (StaticModules[index].name_length == name_length)

My problem is the above line (346) in static.c. The name_length is 7
(svg+xml), which is the mime type of the svg, whereas the
StaticModules.name_length is 3 - SVG.
Since this is the case, the module is not registered, and svg doesnt
work. I can bruteforcefully fix it (by adjusting the string in
StaticModules),
but I want to understand how it is intended to work?

How is this done automatically? Are there any examples? How about documentation?
