  log: "graphics/gifski: update to 1.13.0\n\nThe last bit of C has fallen\n\ngif.ski
    was originally meant to be just the highest-quality GIF maker, but over\ntime
    I also made it generate smaller files. Now it's probably the most\ntechnically
    advanced GIF compressor, if I say so myself.\n\nThe key to good GIF compression
    is making LZW algorithm lossy. In 2014, I wrote\na patch that added lossy compression
    to gifsicle. Gifsicle is a GIF optimization\ntool created in 1998, so I can't
    blame them for not using Rust. Of course,\nI wanted to use that lossy compression
    in gif.ski too, so I've made gifsicle\nusable as a Rust crate.\n\nRust already
    had a gif encoder, so bringing all of the gifsicle's code seemed\nunnecessary.
    I only wanted the lossy LZW bit, so I've made the Rust gif library\naccept data
    from other compressors, and used only a couple of gifsicle's C\nfunctions for
    compression.\n\nThe lossy LZW compressor was still my 2014 hacked-together C â\x80\x94
    until yesterday.\nI've rewritten it in Rust.\n\nThe rewritten code gives exactly
    the same, bit-identical output. Usually, when\npeople rewrite projects it's hard
    to compare results to the original, because\nthe rewrites change and reinvent
    things along the way. This time it's apples to\napples. I made sure it works exactly
    the same. I even reimplemented an integer\noverflow bug and quirks caused by use
    linked lists. The result isâ\x80¦ the same\nperformance, and the same binary size,
    within margin of error. You don't need\nto rush to upgrade! On one hand this isn't
    surprising â\x80\x94 it's the same algorithm,\nand Rust has C-like performance
    as advertised. OTOH I used mostly idiomatic\nRust, and did not try to make it
    super optimized. The original C code did clever\nthings with memory pools and
    linked lists, and I've swapped it all for Vecs in\nenums.\n\nAside from ffmpeg,
    which I'm not rewriting, gif.ski is now 100% pure Rust. It\nmakes it a bit easier
    to build it. The x86-64 MUSL/Linux binary has been built\non my ARM Mac. Since
    the code is now in a form I find easier to refactor, later\nI'll work on improving
    quality of its lossy dithering, because for some reason\nI'm determined to squeeze
    every last possible bit out of this prehistoric video\nformat.\n"
