Thread:Extension talk:NativeSvgHandler/Support for the link parameter/reply (2)

I had this same problem, so I hacked the code quickly: added link wrapper, copied from base MediaTransformOutput class, https://doc.wikimedia.org/mediawiki-core/master/php/html/MediaTransformOutput_8php_source.html

I've submitted a pull request, but in the meantime, interested parties can get my copy from https://github.com/kvand/NativeSvgHandler.
