Add RECT nodes to the scene-graph demo to illustrate how they are used.
Here, we add a solid rectangle behind each surface as a quick-and-dirty
border, handling surface.commit in order to size it appropriately.
If a NULL xkb_rule_names pointer is passed to
xkb_keymap_new_from_names, libxkbcommon will default to reading
the XKB_* env variables. So there's no need to do it ourselves.
Also s/xkb_map_new_from_names/xkb_keymap_new_from_names/ since the
latter is more consistent with the returned struct name.

There is one exception: layer-shell still uses wlr_log. Would need to
convert to fprintf to drop the wlroots dep there.
Fixes: 34e7f69d69 ("examples: remove dependency on wlr_egl from clients")
The specified clients in this commit used to rely on wlr_egl and
some of its related functions in order to render surfaces.
This is no longer the case as of this commit.
Value is now an enum with a new value ("on-demand") that compositors can use to allow "normal" keyboard focus semantics regardless of the layer the client surface is on. An error is sent for invalid keyboard interactivity values. The old behavior is retained for clients using the previous version of the protocol.
Also adjusted the layer-shell example program to use the new keyboard interactivity options.
Client examples using wlr_egl would fail with EGL_BAD_CONFIG because they
need an EGL config. Set the config attribs to a non-NULL value to make
sure wlr_egl creates an EGL config.
Fixes: 037710b1d4 ("render/egl: support config-less wlr_egl")
This callback allowed compositors to customize the EGL config used by
the renderer. However with renderer v6 EGL configs aren't used anymore.
Instead, buffers are allocated via GBM and GL FBOs are rendered to. So
customizing the EGL config is a no-op.
Now that the Wayland backend has moved to wlr_swapchain, only
client examples use the dependency. Stop linking against wayland-egl
in the wlroots library.
This example was relying on wl_display_dispatch being enough to fetch
output information. This worked by chance.
Add an explicit wl_display_roundtrip.
Other examples don't setup wl_output listeners, so they should be fine.
Fixes: 297354f847 ("Remove unnecessary wl_display_dispatch calls")
Closes: https://github.com/swaywm/wlroots/issues/2386
