e.g. 512px, 1024px, 2048px
I wanted to get a high-res version to set as a file icon in OSX, but the highest resolution I found here was 208px. I don't have Photoshop, and in any case it would be nice if it were easy to get them off the internet.
These don't need to be in the repo (at least not on the master branch), but they could be added as downloads on GitHub (or elsewhere).
I have 1664x1024 versions (based on the SVG) in my hq branch.
Simple PNG images of that size are still pretty small (those versions are about 30KB each, compared to 512KB for the PSD), so I think they would be worth including in the master branch.
I agree with you. I have merged in the PNGs you included in your pull request.
