A lot of protocols extend the wl_surface state. Such protocols need
to synchronize their extended state with wl_surface.commit and
cached states. Add a new utility for this purpose.
Sadly, the new API is not backwards compatible with the old API. Since
we have already switched all users in wlroots to the new API compositors
are already practically mandated to implement the new API. Let's get rid
of the old one since there is no point.
It turns out we forgot about the function declaration in the header.
Also some docs were still referring to that function.
Move the wlr_output_attach_render() docs to
wlr_output_begin_render_pass().
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.
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.
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.
We can just assume CLOCK_MONOTONIC everywhere.
Simplifies the backend API, and fixes clock mismatches when multiple
backends are used together with different clocks.
