Post #2590797

Forgot to include in the stats that I encountered at least 5 bugs when implementing the mixing from the article — filled four (though one was a duplicate of another), and posted my test case into another pre-existing report. And there might've been bugs that I already knew about, so I just worked around them (like with all the `tan(atan2())` stuff). Ah, and also at least one bug that was only in an older version of a Chrome, but fixed in Canary, so did not report it.
