Had to test a fix from while I was in ZZZ on Windows. Booted up and installed both a Firefox + SVG build and Adobe SVG, then started testing. Rather more silly little bugs had crept in than I was expecting. Especially poor results with the Firefox + SVG build... it really doesn't look likely they've come very far, though it's no longer crashing the browser, it doesn't appear to support any javascript-ed animation.

Anyway, spent the rest of the day working on fixing the bugs that showed up, having to work in Windows most of the time, which meant getting everything re-synced and re-set-up over there. Happily I'm back on Linux now :) .
