I was fixing the bug about the svg version attribute not always being written, and came across two issues. The first is minor, but the second is one for a bit of collaboration.
First is that I found our default version we've been adding is "1.0". Thus we end up with <svg = "1.0", whereas it really needed to be updated to "1.1". That bit of code has not been touched since Mental first imported things, so I'm very sure it is just an oversight.
The second is that we are still adding this to every file:
sodipodi:version="0.32"
Is it safe to remove that now? I'm pretty sure we don't need to keep compatibility with SodiPodi anymore. I'd like to be about to clean up our use of the "sodipodi" namespace altogether... but that is really a large and involved task and most likely not one for now.
