This commit adds support for the river-xkb-config-v1 protocol. There's
a new keyboard_layout block in config that can take options from
xkeyboard-config(7).
Recently, river removed the hardcoded Ctrl+Alt Delete keybinding that
exits river and replaces it with a new `exit_session` request. This adds
support for that request via the new `exit_session` bind. We also added
3 hardcoded default keybinds to: exit river, reload the config, and
open foot. This way, if the config fails to load or is missing, you
should still be able to try reload. I guess you're still SOL if you have
at least one keybind and it's not reload_config, but you do what you can
do.
Right now, the support is still incomplete (no way to set config) but
we get the devices and set them up and handle current/support events
for the river_libinput_device_v1 devices.
Added pixman and zigimg dependencies
Set up in build.zig, added to both exe and exe_check
Add new protocols:
river-layer-shell-v1
wlr-layer-shell-unstable-v1
xdg-shell (dep of wlr-layer-shell-unstable-v1)
Update Context.zig to hold wl_output, wl_shm, and a WallpaperImage
Also re-ordered all of its fields into alphabetical order
Context.create() now takes a Context.Options struct so that it takes
one arg instead of many smaller args.
Added new WallpaperImage.zig, but it's not yet actually used
