The SVG needed some serious massaging. Affinity doesn't want to export
svgs with clip paths, for some reason, and rasterizes them. Clip paths
however work in Firefox, BUT they cannot have style tags, which cause
the clipped region to vanish.
I made this by taking the logo with text (which has the soft drip),
removing the text, exporting to svg with nothing removed, then fixing it
in inkscape so it actually works in the browser, then finally running it
through svgo.
