archive tag lines don't work in FF/inconsistent on iOS/blurry on retina/crappy performance — convert to SVG?

also, a thought on a more efficient way to do this:

instead of making jquery search for every instance of a hovered tag AND then get the coordinates AND then draw the lines, make an array of project names, tags, and px whenever isotope relay outs and then use that? works as a kind of cache of the first two steps, instead just look up projects with tag and draw btwn their px
