CanvasProxy feature is being removed to make room for a newer\r\nincarnation known as OffscreenCanvas, which will be added soon.\r\nDraft Proposal: https://wiki.whatwg.org/wiki/OffscreenCanvas\r\nThere are currently no known implementations of CanvasProxy.\r\n\r\nSummary of changes:\r\n* Remove CanvasProxy and all canvas methods related to CanvasProxy\r\n* Remove the notion of a CanvasRenderingContext2D being in a proxied\r\n  state.\r\n* Remove the notion of a CanvasRenderingContext2D being in an indirect\r\n  state.\r\n* Remove the notion of a \"scratch bitmap\" from CanvasRenderingContext2D\r\n  and use a single concept of an \"output bitmap\" everywhere.\r\n* Remove the notion of a \"list of pending user interface actions\"\r\n* Remove the notion canvas context bindinding, no more standalone\r\n  contexts, no more setContext method on canvas.\r\n* Remove the commit() method of CanvasRenderingContext2D.\r\n* Remove the CanvasRenderingContext2D constructor.\r\n* Removed the notion of concept-canvas-context-bitmap-mode, canvii\r\n  now always behave as what was previous described as \"fixed\" mode.\r\n* Rename bitmap modes \"direct-2d\" and \"direct-webgl\" to just \"2d\" and\r\n  \"webgl\" respectively.\r\n*The hit region list, alpha flag, and origin-clean flag are now internal attributes of CanvasRenderingContext2D, rather than attributes of the scratch/output bitmaps.","created_at":"2016-03-02T22:49:28Z","updated_at":"2016-03-02T23:28:21Z","closed_at":null,"merged_at":null,"merge_commit_sha":"7690a60f14b291f1fea309e4335e036242388089","assignee":null,"milestone":null,"commits_url":"https://api.github.com/repos/whatwg/html/pulls/790/commits","review_comments_url":"https://api.github.com/repos/whatwg/html/pulls/790/comments","review_comment_url":"https://api.github.com/repos/whatwg/html/pulls/comments{/number}","comments_url":"https://api.github.com/repos/whatwg/html/issues/790/comments","statuses_url":"https://api.github.com/repos/whatwg/html/statuses/1108fcb6901686825a543d3a391604107acc2e50","head":{"label":"junov:removeproxy","ref":"removeproxy","sha":"1108fcb6901686825a543d3a391604107acc2e50","user":{"login":"junov","id":2607864,"avatar_url":"https://avatars.githubusercontent.com/u/2607864?v=3","gravatar_id":"","url":"https://api.github.com/users/junov","html_url":"https://github.com/junov","followers_url":"https://api.github.com/users/junov/followers","following_url":"https://api.github.com/users/junov/following{/other_user}","gists_url":"https://api.github.com/users/junov/gists{/gist_id}","starred_url":"https://api.github.com/users/junov/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/junov/subscriptions","organizations_url":"https://api.github.com/users/junov/orgs","repos_url":"https://api.github.com/users/junov/repos","events_url":"https://api.github.com/users/junov/events{/privacy}","received_events_url":"https://api.github.com/users/junov/received_events","type":"User","site_admin":false},"repo":{"id":46513253,"name":"html","full_name":"junov/html","owner":{"login":"junov","id":2607864,"avatar_url":"https://avatars.githubusercontent.com/u/2607864?v=3","gravatar_id":"","url":"https://api.github.com/users/junov","html_url":"https://github.com/junov","followers_url":"https://api.github.com/users/junov/followers","following_url":"https://api.github.com/users/junov/following{/other_user}","gists_url":"https://api.github.com/users/junov/gists{/gist_id}","starred_url":"https://api.github.com/users/junov/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/junov/subscriptions","organizations_url":"https://api.github.com/users/junov/orgs","repos_url":"https://api.github.com/users/junov/repos","events_url":"https://api.github.com/users/junov/events{/privacy}","received_events_url":"https://api.github.com/users/junov/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/junov/html","description":"HTML
