sway-1.10 doesn't support ICC, sway-git does

I've used sway-git for a while for its new ICC color profile support. As Sway 1.10 is now added to extra-testing, I've used that. Unfortunately, setting ICC profiles doesn't seem to do anything.

MWE:

Switch color profile:

```
$ swaymsg output '*' color_profile icc /usr/share/color/icc/colord/some-profile.icc
```

Back to default:

```
swaymsg output '*' color_profile srgb
```

Any thoughts?

Compare both PKGBUILDs and see if it's something with the package, if not, wait for the new feature to become stable upstream or use the git package.

Based on the upstream discussion it looks like it only works with the vulkan renderer not gles.  Have you tried specifying the renderer?  (e.g., `WLR_RENDERER=vulkan sway`)

The renderer was the problem indeed.

I had set
```
Exec=env WLR_RENDERER=vulkan sway
```

in `/usr/share/wayland-sessions/sway.desktop`, but that file was overridden when moving from sway-git to sway. Adding it back fixes the problem.

Should I put the env variable some other place?
