These tests all have equivalents in the WebGL CTS (dom/canvas/test/webgl-conf), fwiw!

While we are in soft freeze cycle, can we please hold off the patch re-land after that? Thanks.

Sorry we missed this comment before relanding. Hopefully it isn't a problem to keep this, but if it is we can back out again.

No worries. I was thinking about not to (potentially) impact RelEng work for channel merge, especially it got backed out twice that showed some concerns. If try results look good, it's not a problem to keep this. Hope this time we get everything right.
