When incorporating this code, care needs to be taken to not lose the optimizations John Bauman added in Bug 66884, associated Chromium bug http://crbug.com/92388 . He indicated offline that he tested with http://jsperf.com/webgl-teximage2d-vs-texsubimage2d/2 (and possibly other versions of the test) as well as webgl-ios-rage. He also indicates: "part of my fix should become redundant due to the fact that they're never copying to an intermediate buffer, and you should be able to modify unpack<BGRA8, uint8_t, uint8_t> to use the faster BGRA->RGBA conversion".
