aacdc0b6f1 wayland: Apply states without needing a newly attached buffer
Applying some states, such as the minimum and maximum toplevel size, do not
require a new buffer and can operate on the old buffer. Requiring a client
to commit a new buffer just to change such states prevents setting limits
on an already existing surface buffer.

eaa6efef56 wayland/window: Don't lose precision in MetaWaylandWindowConfiguration
Commit 8bdd2aa7 would offset the window position by the difference
between the configured window size and the committed size from the
client to prevent the window from drifting while resizing.

This, however, did not take into account the actual geometry scale, so
when using any scale greater than 1, the window would rapidly drift away
due to that offset.

In order to solve this, we need to make sure we store away the pending
window configuration in the stage coordinate space, in order to not
loose precision. When we then calculate the offset given the result from
the client, it'll use the right scalars, while before, one scalar was in
surface coordinates, while the other in stage coordinates.

066bc5986d wayland: Drive frame callbacks from stage updates
Don't tie frame callbacks to actor painting, as it may end up in
situations where we miss sending frame callbacks when we should have. An
example of this is when a surface is partially off screen, and then
reports damage that is fully off screen. When this happen, we are likely
not to repaint anything, thus we won't send any frame callbacks even
though it's "suitable" for rendering again, as the surface is not on a
separate workspace or fully obscured.

47002bf0cd wayland/surface: Put buffer reference on heap
Currently a buffer use count always reaches zero before it is replaced.
This is due to the fact that at the point a new buffer is attached, the
last potential user releases it (the stage) since the currently
displayed frame has a composited copy of the buffer.

This may however change, if a buffer is scanned out directly, meaning it
should not be released until the page flip callback is invoked.

Prepare for this by making the buffer reference a heap allocated struct,
enabling us to keep a pointer to it longer than the buffer is attached.

c0c74484bc wayland: Don't access MetaWaylandSurface::window directly
It'll be moved to the role owning it, accessed via a helper function
implemented by the role. Currently it still just fetches the field in

d02c124e1d wayland/surface-role: Rename commit() vfunc apply_state()
The vfunc is not called when a surface commits its state, but when the
state is applied. Make this clearer by changing the name to
"apply_state" (and "pre_apply_state").

554644f9e0 wayland: Rework asynchronous window configuration
This changes how asynchronous window configuration works. Prior to this
commit, it worked by MetaWindowWayland remembering the last
configuration it sent, then when the Wayland client got back to it, it
tried to figure out whether it was a acknowledgment of the configuration
or not, and finish the move. This failed if the client had acknowledged
a configuration older than the last one sent, and it had hacks to
somewhat deal with wl_shell's lack of configuration serial numbers.

This commits scraps that and makes the MetaWindowWayland take ownership
of sent configurations, including generating serial numbers. The
wl_shell implementation is changed to emulate serial numbers (assuming
each commit acknowledges the last sent configure event). Each
configuration sent to the client is kept around until the client one. At
this point, the position used for that particular configuration is used
when applying the acknowledged state, meaning cases where we have
already sent a new configuration when the client acknowledges a previous
one, we'll still use the correct position for the window.

cb91f44ba4 wayland/wl-shell: Use input region as window geometry if set
Historically, wl_shell clients used to pretend the input region was
equivalent to the window geometry, so for "correctness" lets do that
here too. This makes wl_shell clients with drop shadow behave marginally
better than before.

bbec8abb68 wayland/surface: Rename MetaWaylandPendingState to MetaWaylandSurfaceState
The name didn't communicate it was about surface state, and it somewhat
confusingly had the name "pending" in it, which could be confused with
the fact that while it's used to collect pending state, it's also used
to cache previously committed pending state.

4bacb3621b window/wayland: Make .._wayland_move_resize() name more explanatory
The intention of meta_window_wayland_move_resize() is to finish a
move-resize requested previously, e.g. by a state change, or a
interactive resize. Make the function name carry this intention, by
renaming it to meta_window_wayland_finish_move_resize().

b5f50028f2 wayland: Untie MetaWindowXwayland lifetime from the wl_surface
For the most part, a MetaWindow is expected to live roughly as long as
the associated wl_surface, give or take asynchronous API discrepancies.

The exception to this rule is handling of reparenting when decorating or
undecorating a window, when a MetaWindow on X11 is made to survive the
unmap/map cycle. The fact that this didn't hold on Wayland caused
various issues, such as a feedback loop where the X11 window kept being
remapped. By making the MetaWindow lifetime for Xwayland windows being
the same as they are on plain X11, we remove the different semantics
here, which seem to lower the risk of hitting the race condition causing
the feedback loop mentioned above.

What this commit do is separate MetaWindow lifetime handling between
native Wayland windows and Xwayland windows. Wayland windows are handled
just as they were, i.e. unmanaged together as part of the wl_surface
destruction; while during the Xwayland wl_surface destruction, the
MetaWindow <-> MetaWaylandSurface association is simply broken.

44624736c5 wayland: Push actor state instead of itself pulling
Make the Wayland objects push the state relevant to their role to the
MetaSurfaceActor instead of MetaSurfaceActorWayland pulling the state
from the associated surface.

This makes the relationship between the actor and the objects that
constructs it more clear; the actor is a drawable that the protocol
objects control, not the other way around.

This will make it easier to "detach" a surface actor from a surface,
which is necessary when unmapping a window while the underlying surface
is yet to be destroyed and potentially reused.

1c8aebd811 wayland: Ensure wl_shell_surfaces are set reactive
Wayland clients using the wl_shell interface were never receiving mouse
input. It meant they also couldn't be raised with a click.

This was because the call to meta_wayland_surface_set_window for wl_shell
surfaces did nothing while surface->window == window already. As such, it
never called clutter_actor_set_reactive() and the wl_shell window remained
a non-reactive actor.

Just make sure surface->window isn't already set before calling
meta_wayland_surface_set_window so it can actually do what it's meant to.

7fd585fe98 wayland: Split out shell surface code from meta-wayland-surface.c
Move xdg_shell related functionality to a new meta-wayland-xdg-shell.c
and wl_shell related functionality to a new meta-wayland-wl-shell.c,
and adapt role object tree.

Common functionality related to the surface being drawn as a
MetaSurfaceActor was moved to a MetaWaylandSurfaceRoleActorSurface role.

The subsurface role GObject is made to inherit the actor surface GObject.

Shell surface hooks (configure, ping, close, popup done) were added to
a MetaWaylandSurfaceRoleShellSurface GObject which inherits the
surface actor role GObject.

The shell surface roles (xdg_surface, xdg_popup, wl_shell_surface) are
made to inherit the shell surface GObject and implement the relevant
API.
