--- Comment #2 from Brion Vibber <[email protected]> ---
Note the general problem with APNG->GIF is that you may have to apply two lossy
transformations:

* color quantization to an 8-bit palette, probably with dithering
* 8 or 16-bit alpha channel -> 1-bit alpha channel

Both of these will potentially leave a GIF version looking like crap, and most
people will get the crappy version. :(


I'd kinda prefer to phase out animated GIF in favor of proper video formats,
editable slideshows of static images, or animated SVG... introducing APNG
basically just gives us a slightly better animated GIF exclusively for Firefox
users.
