I haven't seen anything that depends on CanvasPixelArray the name, but I wonder if people use the constructor to access the CPA prototype?  It could be treated simply as an alias to the appropriate Typed Array constructor i guess, but i'd want to be sure that there's no weirdness with people modifiying both the typed array and cpa prototypes.
