hdrfix. it's my hdrfix utility that's pulling in nightly rust

probably for something that needed nightly 3 years ago lol

i'll futz with that later

@brooke What are you doing with hdrfix?
@ePirat i'm taking the .png snapshots that VLC produces from my Ultra HD movies, color-correcting them, and outputting ready-to-post .jpegs :D
@brooke I wonder if you could achieve the same with vf_libplacebo in FFmpeg?

@ePirat pretty sure you can!

(my original target with hdrfix was .jxr screenshots from HDR gaming on Windows, it just happens to also work for this case handily without remembering the ffmpeg filter syntax ;) )

@brooke Did you publish it or is it just some private personal tool?
@ePirat it's published on crates.io but i mostly keep it around for myself and other flight simulator nerds on the msfs forum who sometimes ask how to fix their screenshots for posting :D
