Network graph <canvas> styling

Not sure if it can be done, but I'll look into styling this canvas here later:

Looks like my SVG invert filter actually works on a <canvas>, but just applying that plain invert filter arguably makes the network graph worse than before. I'll have to dig deeper into SVG filters and am pretty certain that an acceptable result can be reached. :)

Some progess here, I made a feColorMatrix generator (might not work on Chrome). Now we just need to find satisfying slider values.

Meh, It seems like feColorMatrix isn't exactly suited for this and something like feComponentTransfer might be more appropriate to just darken the brighter parts of that canvas.

Either way, these filters would mess with the user avatars and font antialiasing, so it's probably not worth trying to get them right.

I'll probably just go with slightly reduced opacity to darken it just a bit.
