This adds an alternate way to use wlr_damage_ring without the
concept of buffer age. Buffer age is a concept inherited from EGL
but there is no real reason why we should continue to use that in
wlroots. Instead, use wlr_buffer pointers.
Eventually, we should be able to remove the buffer age based
functions.
If the external-only flag is set, then the EGLImage is only
supported for use with GL_TEXTURE_EXTERNAL_OES texture targets.
In particular, the EGLImage cannot be bound to a RBO.
RMFB implicitly performs a modeset to turn off any CRTC which is
using the FB. This prevents seamless transitions between two DRM
masters from working.
Use the new CLOSEFB IOCTL which doesn't turn off anything and leave
it up to the compositor to turn off outputs on shutdown if it wants
to.
It's possible that we don't have an EGLDevice if we created the
EGL context from a GBM device. Let's ensure all GPU-accelerated
renderers always have a DRM FD to return by falling back to GBM's
FD.
Instead, move the wlr_xwayland_surface_set_withdrawn() and
wlr_xwayland_surface_restack() calls to the MapNotify handler with an
override_redirect check, as they are done too early. This mirrors the logic in
the UnmapNotify handler and fixes a bug where wlr_xwayland_surface_restack()
would be called on an o-r window after the following sequence of requests:
- CreateWindow with override_redirect=True
- ChangeWindowAttributes with override_redirect=False
- MapWindow
Fixes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3770
Under X11, ConfigureNotify means that the window has already been resized.
Sending ConfigureRequest with the received size is not only useless, but also
can confuse the window manager, which will probably reply with the current
(i.e. *old*) size causing a configure loop.

new_subsurface emitted immediately isn't actually that useful. Revert the change
and document that this event is special.
This reverts commit 504b9491f0.
This commit changes the behavior of `new_*` signals to better match
their names (see https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3608).
wlr_xdg_shell.events.new_surface is now emitted when an xdg_surface is
created, and wlr_xdg_shell.events.new_{toplevel,popup} events are
introduced to get notified when an xdg_{toplevel,popup} is created.
Same applies to
`wlr_xdg_decoration_manager_v1.events.new_toplevel_decoration`. As a
result, wlr_xdg_surface.added and wlr_xdg_toplevel_decoration_v1.added
are removed, as we no longer need to track whether the corresponding
event was emitted.
Additionally, this commit changes the behavior of
wlr_xdg_surface.events.destroy: it is now emitted when the xdg_surface
is destroyed, as the name suggests.
wlr_xdg_{toplevel,popup}.events.destroy events are added to get
notified when an xdg_{toplevel,popup} is destroyed.
The wl_display destroy listener cleans up the global (if any).
wlr_output.display will go away, so setup the listener in
wlr_output_create_global() instead of wlr_output_init().
Currently wlr_output holds a wl_display, but it will go away soon.
Instead of relying on that field in wlr_output_create_global(),
make the dependency explicit by taking a wl_display as argument.
wl_display holds a lot more than wlr_session needs: wlr_session
only needs to wait for a FD to become readable, but wl_display
provides full access to the Wayland client and protocol objects.
Switch to wl_event_loop to better reflect the above.
While the xdg-shell protocol requires this, it does not yet have
a dedicated error code for invalid titles; this commit makes
wlroots send a generic error instead.
