This is how browsers perform color management. They treat
gamma-corrected sRGB colors as if they were linear RGB.
Correctness aside, this mode is introduced for legacy reasons. Most
UI/UX tooling uses this color management as well, and many have created
an intuition about how color should behave from interacting with a
browser.
This feature flag should facilitate application development with `iced`
in those cases.
