WebGL suggests they don't which creates interesting scenarios as to what happens when you get a 2D context, then a WebGL one, and then start drawing on the 2D one, etc. Ideally all contexts share the same bitmap I think, but state of the art might make this impractical? :/ 30640 1 ian 2010-01-06 11:10:22 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment. If you are satisfied with this response, please change the state of this bug to CLOSED. If you have additional information and would like the editor to reconsider, please reopen this bug. If you would like to escalate the issue to the full HTML Working Group, please add the TrackerRequest keyword to this bug, and suggest title and text for the tracker issue; or you may create a tracker issue yourself, if you are able to do so. For more details, see this document: http://dev.w3.org/html5/decision-policy/decision-policy.html Status: Rejected Change Description: no spec change Rationale: The spec is clear that there is a single bitmap (see the first dozen or so paragraphs of the <canvas> element's definition — it talks about "the" bitmap everywhere, independent of the contexts, which it refers to in the plural). If this isn't going to work for WebGL, I need to know what WebGL needs from the spec to make it all work.
