To be ready to catch up on Athens when it will be default rendering engine, you may want have source icon as svg and exported as png with Inkscape. I use this set up for iStoa clipart, oversampled as bitmap for a Nexus 5 screen display resolution, then downscaled at load time to the used display resolution.

Hi Phil,

I mostly just use Gimp, but that is not a very efficient and effective solution. Most icons, especially those in flat styles, should be rendered/generated from a vector format instead of from a bitmap. They should be programmed, to be themable. Fontographer is actually a much better tool for the kind of icons found in bootstrap like styles
