Is there an SVG source from which the toggle icon can be re-rendered at @2x for retina displays?
Don't actually know, since the map minimising originally came in from pull request #8. Hey @ktraff, can you weigh in on this?
All I have is the png unfortunately, though I agree it'd be better to replace this with SVG.
Did you get the icon from somewhere or draw it yourself?
I believe I pulled this from a Google image search originally.
wooo @ktraff hope that did not require attribution then.
