upgrades wcslib to the latest version that doesn't require significant changes on our end.  wcslib 5.4 (the current latest release) handles SIP itself, so we need to carefully *not* handle SIP on our end any longer in that case, and still retain the same API (that's the tricky bit).\r\n\r\nIn any event, this PR is designed to be something low-risk to merge in the meantime, as wcslib 5.4 support may take some time to complete."},"comment":{"url":"https://api.github.com/repos/astropy/astropy/issues/comments/109747772","html_url":"https://github.com/astropy/astropy/pull/3751#issuecomment-109747772","issue_url":"https://api.github.com/repos/astropy/astropy/issues/3751","id":109747772,"user":{"login":"mdboom","id":38294,"avatar_url":"https://avatars.githubusercontent.com/u/38294?v=3","gravatar_id":"","url":"https://api.github.com/users/mdboom","html_url":"https://github.com/mdboom","followers_url":"https://api.github.com/users/mdboom/followers","following_url":"https://api.github.com/users/mdboom/following{/other_user}","gists_url":"https://api.github.com/users/mdboom/gists{/gist_id}","starred_url":"https://api.github.com/users/mdboom/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mdboom/subscriptions","organizations_url":"https://api.github.com/users/mdboom/orgs","repos_url":"https://api.github.com/users/mdboom/repos","events_url":"https://api.github.com/users/mdboom/events{/privacy}","received_events_url":"https://api.github.com/users/mdboom/received_events","type":"User","site_admin":false},"created_at":"2015-06-07T12:32:00Z","updated_at":"2015-06-07T12:32:00Z","body":"
