It was completely wrong: according to the protocol, the effective
geometry is only updated on commit time if there pending state has
new state from xdg_surface.set_window_geometry or
xdg_surface.set_window_geometry has never been sent at all.
This commit adds wlr_xdg_surface.geometry which correctly matches the
effective window geometry and removes now-useless
wlr_xdg_surface_get_geometry().
It seems that some scene compositors want to avoid wlr_scene_output_commit
and use the lower lever wlr_scene_output_build_state. However, build
state does not early return if a frame is not needed so compositors will
implement the check themselves. Let's add a helper function that compositors
can use to implement the check.
Technically pending_commit_damage is a private interface, so this lets
compositors not interface with private interfaces to implement the check.
This commit removes extra wlr_xdg_toplevel_set_parent() calls,
simplifies wlr_surface->wlr_xdg_toplevel conversion logic, makes related
structures store wlr_xdg_toplevel objects directly instead of
wlr_surface objects, and improves the code style.
This swaps the argument order of wlr_surface_accepts_touch() and
wlr_surface_accepts_tablet_v2(), putting the wlr_surface argument first
as should be the case for functions namespaced with wlr_surface_*.
This will let compositors know if changing adaptive_sync state has any
chance of working. When false, then the current state is the only
supported state, including if adaptive_sync is currently enabled as is
the case for Wayland and X11 backends.
When true, changing state might succeed, but no guarantee is made. It
just indicates that the backend does not already know it to be
impossible.
The surface argument is only used to obtain a wlr_seat_client and
semantically makes no sense. The wl_touch.cancel event applies to all
touch points and all surfaces of a client.
I decided to make the functions accept a wlr_seat_client rather than a
wl_client as it is directly available in the wlr_touch_point struct and
simplifies the implementation.
This is worth doing despite wl_client_get_destroy_listener() incorrectly
accepting a mutable wl_client pointer since this lookup_client()
function will primarily be used with a wl_display_global_filter_func_t
which only provides a const wl_client pointer.
Work around this libwayland API wart in wlroots so compositors don't
have to.
I wish to use a allowlist of globals for my security context
implementation rather than a blocklist, which means I need access to
the wp_single_pixel_buffer_manager_v1 global in order to allowlist it.
I think using a allowlist will make it harder for me to accidentally
expose globals to a security context that were meant to be restricted.

This new helper assists compositors in allocating buffers for
modesets. It degrades to different allocation parameters as
needed, and should help with screens not turning on when multiple
outputs are connected on some hardware (e.g. Intel).
For simplicity, the old logic to try allocating with explicit
modifiers first and then fallback to implicit modifiers later is
left as-is. We'll probably want to have more complicated logic
instead in the future: try the fallback on one output at a time,
and try dropping modifiers one by one instead of using implicit
modifiers (at the cost of some combinatorial explosion).

This allows us to remove the renderer destroy listener. The
listener was buggy: compositors can't destroy surface resources on
their own.
The wlr_compositor will always outlive the wlr_surface, so no need
for a destroy listener.
