Comment (by SirLouen):

 @siliconforks got your point

 Now, I'm even more curious about how `png8` is working behind the scenes.

 Anyway, can you refresh to me the reason of quantizing and then forcing
 `png8` afterwards, specifically for greyscale images? I remember there was
 a reason, but I've read through the thread, but I can't completely remind
 why this was useful.
