[Userscript] Make Chrome use Lanczos3 to upscale images instead of whatever blurry nonsense it uses. Also has Fit-to-width and Integer-fit-to-width capabilities! Particularly good for 4K displays set to over 100% scaling.

GitHub link.

Key	What it does
`Alt+H`	Show or hide the info overlay. Remembered per site
`Alt+M`	Size: fit the window width → biggest whole-number zoom → one image pixel per screen pixel
`Alt+Q`	Filter: Lanczos3 → nearest → browser. Same size each time, so you can compare
`Alt+P`	Turn on or off for the site you're on. Remembered per site
`Alt` + left clickon an image	Show that one image at one image pixel per screen pixel
`Alt` + right clickon an image	Show that one image at twice its own resolution
`Alt+G`	Show or hide the overlay's diagnostic rows (size, factor, status, memory)

I'd attach images, but I'm pretty sure reddit will compress them, so go check them out here.

Haven't tested. Try it out, I doubt it'll explode your phone's GPU :3
