Should I bother adding qoi support? My gut feeling is that it's a pretty meh codec that doesn't push any of the existing boundaries. Does anyone use it at all?
It's actually quite annoying how much attention and widespread adoption it's gotten, when far more viable improvements are right there on the table, but no one's interested in them.
For example, I took my 16k square test image and saved it in gimp with 0 compression, resulting in a 1 GB file. This presumably applies the png filters, but skips deflate. Then I did this:
gzip -9:
57 MB, 59.8 s to save, 2.6 s to load.
zstd -18:
43 MB, 25.9 s to save, 0.28 s to load.
xz -9:
39 MB, 17.3 s to save, 0.48 s to load.
@wolfpld none of those have a specification that fits on one page
