Description John Bauman 2011-03-01 14:27:57 PST 
Currently every WebGL context's premultipliedAlpha is forced to true in the WebKit's OpenGL context implementation (used on Macs). premultipliedAlpha=false is required to be supported by the OpenGL spec.

Actually, nevermind. I've fixed the premultipliedAlpha flag to not be forced on, but the compositing of the data still ignores the flag.
