I wasn't able to find it.\r\n\r\nI simply want to know how to ask u8glib for the current page's bounds during the draw loop so that we can have the screen update code in Marlin draw only the items that are within the page being rendered. This way we can save cycles in the draw loop, which is a major bottleneck, especially on deltabots with graphical displays.\r\n\r\nOr, if we can't ask for the current page bounds directly, then at least be able to pre-determine the page size, number of loops, whether it's being drawn bottom-to-top, etc.\r\n\r\nThanks for any guidance you can provide!"},"comment":{"url":"https://api.github.com/repos/olikraus/u8glib/issues/comments/262693928","html_url":"https://github.com/olikraus/u8glib/issues/447#issuecomment-262693928","issue_url":"https://api.github.com/repos/olikraus/u8glib/issues/447","id":262693928,"user":{"login":"olikraus","id":1084992,"avatar_url":"https://avatars.githubusercontent.com/u/1084992?v=3","gravatar_id":"","url":"https://api.github.com/users/olikraus","html_url":"https://github.com/olikraus","followers_url":"https://api.github.com/users/olikraus/followers","following_url":"https://api.github.com/users/olikraus/following{/other_user}","gists_url":"https://api.github.com/users/olikraus/gists{/gist_id}","starred_url":"https://api.github.com/users/olikraus/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/olikraus/subscriptions","organizations_url":"https://api.github.com/users/olikraus/orgs","repos_url":"https://api.github.com/users/olikraus/repos","events_url":"https://api.github.com/users/olikraus/events{/privacy}","received_events_url":"https://api.github.com/users/olikraus/received_events","type":"User","site_admin":false},"created_at":"2016-11-24T05:34:04Z","updated_at":"2016-11-24T05:34:04Z","body":"Btw...
