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.

On wayland keys correspond to <input-event-codes.h>,
and they are past the limit of u8, causing the
back and forward buttons to be 20 and 19 which definitely isn't right
(they should all be around 0x110..=0x117).
...instead of just from function pointers.
I'm making this change not because I actually want to pass a closure,
but to make passing a single fixed function work. This commit also
simplifies the scrollable example slightly, and without the other half
of this change that simplified example fails to compile with:
```

```
This happens because `progress_bar_custom_style` by itself is a function
item, which is typically coerced to a function pointer when one is
needed, but not in this case. It is possible to work around this on the
caller's side, but especially since the compiler diagnostic for this is
a bit rough (see https://github.com/rust-lang/rust/issues/100116) let's
try to make it work out of the box.
