A struct wlr_xdg_toplevel_configure is passed in with the whole
state. This makes it a lot clearer that the size and WM state are
always sent to the client.
The page_flip can be destroyed, but it is unconditionally accessed later
on when setting present_flags. Fix this by simply setting the
present_flags before the page_flip gets destroyed.
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 fixes direct scanout VRR. As direct scanout buffers are not part
of the swapchain, we would mistakenly union instead of subtract the damage
meaning it will just accumulate indefinitely.
The reason for this existing in the first place is for compositors that
might want to sidestep scene and commit their own buffers to the output.
In this case, scene could theoretically acknowledge that and update the
damage. Except, this really didn't work because WLR_OUTPUT_STATE_DAMAGE
would need to be defined which is optional. This patch also properly
acknowledges commits without damage.
In the use case of a weird compositor that might want to sidestep scene,
they can just trash the damage ring themselves.
Fixes: #3871
There were two problems with the old implementation:
1. wlr_scene_output_commit would bail early if a frame wasn't requested
and there was no commit damage, however commit damage could never accumulate
until rendering happens. The check was subtly wrong as a result.
2. Previously, we would fill the pending commit damage based on the
current state of the damage ring. However, during direct scanout, the
damage would accumulate which would mean we would submit damage from
previous frames even if we didn't need to.
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.
Without this patch, a client calling handle.destroy() will trigger
an assert in libwayland due to a NULL pointer for the destroy handler.
Also implement a missing .destroy handler for the manager itself
and delay destruction of the manager resource from the .stop handler
to the .destroy handler.
The infrastructure to read _NET_WM_WINDOW_TYPE already exists in wlroots
(it's used for example in wlr_xwayland_or_surface_wants_focus()). But
the window type isn't easily accessible to the compositor because the
atoms to compare against are private to xwm.c.
labwc has recently gone to a fair amount of effort (including opening a
whole new xcb connection) just to get the needed window type atoms:
a04b394e59
It seems much cleaner to add the remaining few (3) atoms to wlroots and
implement a shared function which can be used by any wlroots compositor.
v2: naming updates
This fixes two problems:
- A surface could get unexpected release events for buttons pressed
while other surface was focused;
- Clearing focus while a button is pressed would lead to the button
getting "stuck".

Previously it was supplying a pointer to private struct wlr_xwm
which was useless for compositors. The wlr_xwayland pointer in
contrast does have a generic data field and thus can be used by
compositors to attach their own pointer.
Additionally change the return value from int to bool.
This is especially useful if the compositor wants to support X11
panels to control windows. Without the signal a compositor does
have to hook into the user_event_handler callback but that would
not change the _NET_SUPPORTED root window property.
