Currently authors do this by calling <canvas>.getContext, but this can be very expensive. Dean proposed adding a supportsContext method in http://lists.w3.org/Archives/Public/public-html/2012Sep/0119.html Ian added <canvas>.supportsContext in r7482 of the WHATWG spec: http://html5.org/r/7482 https://github.com/w3c/html/commit/6e1081a860afd08e6aa0329032c9cf4106760a27 The work to implement <canvas>.supportsContext in WebKit is being tracked in https://bugs.webkit.org/show_bug.cgi?id=70117 We should consider pulling this in for HTML5. -- You are receiving this mail because: You are on the CC list for the bug.
