It is interesting to see the HTML 5 compatibility charts (including for canvas) according to w3.org here: http://test.w3.org/html/tests/reporting/report.htm ht

  While that is true, I think the chart is misleading in that it doesn't properly weight the tests. Failing to have any sort of globalCompositeOperation is a huge thing, but IE only lost one point for it. I would say that some of the things that the other browsers got dinged for are much smaller in comparison.

    You could argue about the weightings all day though. Will people actually use every single one of those composite operations in real life? Shouldn't the important ones be weighed more? etc.

  FYI, that test suite is said to be about 0.1% complete. Yes, you read that right. No browser is remotely that compliant. Microsoft already idiotically used that suite to declare themselves king of canvas http://www.pcworld.com/businesscenter/article/209787/no_html5_crown_for_ie9_yet_w3c_says.html http://www.pcworld.com/businesscenter/article/209787/no_html... These tests are more involved. Last I checked, no browser gets much more than 80% (though I don't have or want Windows so I can't personally check IE9) http://philip.html5.org/tests/canvas/suite/tests/ http://philip.html5.org/tests/canvas/suite/tests/
