On: Jpegli: A new JPEG coding library

It's regular old JPEG1. I don't know the details, but it turns out that "8 bit" JPEG actually has enough precision in the format to squeeze out another 2.5 bits, as long as both the encoder and the decoder use high precision math.

Wow, this is the first time I heard about that. I wonder if Lightroom uses high precision math.
