I think these are examples of a more general problem, which doopl already mentioned once: 1 pixel is not very visible on devices with such high DPI. As I think doopl suggested, we could scale everything up by the density, i.e. these numbers: http://stackoverflow.com/a/18656286/6540 - otherwise, careful tweaking of each backend would be needed. I already did a little of that, e.g. Twiddle's cursor, but there's plenty more that's a bit rubbish visibility-wise right now."},"comment":{"url":"https://api.github.com/repos/chrisboyle/sgtpuzzles/issues/comments/96371848","html_url":"https://github.com/chrisboyle/sgtpuzzles/issues/212#issuecomment-96371848","issue_url":"https://api.github.com/repos/chrisboyle/sgtpuzzles/issues/212","id":96371848,"user":{"login":"chrisboyle","id":127305,"avatar_url":"https://avatars.githubusercontent.com/u/127305?v=3","gravatar_id":"","url":"https://api.github.com/users/chrisboyle","html_url":"https://github.com/chrisboyle","followers_url":"https://api.github.com/users/chrisboyle/followers","following_url":"https://api.github.com/users/chrisboyle/following{/other_user}","gists_url":"https://api.github.com/users/chrisboyle/gists{/gist_id}","starred_url":"https://api.github.com/users/chrisboyle/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/chrisboyle/subscriptions","organizations_url":"https://api.github.com/users/chrisboyle/orgs","repos_url":"https://api.github.com/users/chrisboyle/repos","events_url":"https://api.github.com/users/chrisboyle/events{/privacy}","received_events_url":"https://api.github.com/users/chrisboyle/received_events","type":"User","site_admin":false},"created_at":"2015-04-26T12:13:24Z","updated_at":"2015-04-26T12:13:24Z","body":"This actually shouldn't be that hard now that zoom works.
