3. Add an optimized path to detect when the YUV overlay can be used to give
the correct rendering, and use it in that case.
This is not a spec issue, it's entirely an implementation issue. You're
welcome to file a bug on that at http://bugzilla.mozilla.org; I can explain

anytime soon unless a volunteer contributes the code.
"He was pierced for our transgressions, he was crushed for our iniquities;
the punishment that brought us peace was upon him, and by his wounds we are
healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
