If at all, it will only create even more visual artifacts due to greatly
reduced colour resolution for nearly-transparent pixels. The point of
not using premultiplied alpha is freedom to change and edit your images,
similar to providing 12, 16 or more bits per colour component. Using 8
bits (or using premulitplied alpha) is simply a performance issue, NOTHING
else.

(Sorry, Nick, when I just re-iterated your point, but I had to provide a
strong "me too" ;-)
