It's mostly equivalent to the case where we've already detached
the pixmap, *except* for the x11_size_changed case. We can simply
detach the pixmap at the time the window changes size, though.

We guarantee ourselves that a valid pixmap will appear any time
that the window is painted. The window actor will be scheduled
for a repaint if it's added / removed from the scene graph, like
during construction, if the size changes, or if we receive damage,
which are the existing use cases where this function is called.
So, I can't see any reason that we queue a redraw in here.
With the split into surface actors, we don't have an easy place
we can use to queue a redraw, and since it's unnecessary, we can
just drop it on the floor.

If the client destroys the pointer resource, we shouldn't unfocus the
surface, and we should regrab it when the client gets the pointer
resource again.
This also fixes a crash at surface destruction because of the unchecked
wl_link_remove that will happen on both pointer and surface destroy.
We can never have a window actor that represents either the X root
window or the stage window, so it doesn't make sense to bail out
early in case we do.
I'd imagine that this came from a much earlier version of the code
where the compositor was much separate and had its own MapNotify
handling.
This reverts commit 283a81eac0.
This can't be done yet, as it will crash when we try to do a destroy
effect from a plugin. The surface actor needs to outlive the surface
in this case.
Though, the unparenting happening is wrong anyway for a destroy effect.
We need to figure out a sane way of doing this unparenting only after
all effects have finished.
As resource destruction can happen in any order at shutdown, we
need to be flexible here. A client disconnecting without cleaning
up all its resources should not assert fail.
Since the unredirected window MetaWindowActor is stacked on top, it
will naturally get culled out of the process, so we can remove the
special casing here. Unfortunately, with the way that the code is
currently structured, it's too difficult to actually prevent setting
the clip / visible regions if the window is redirected, so just let
those be set for unredirected windows for now.
The input region was set on the shaped texture, but the shaped texture
was never picked properly, as it was never set to be reactive. Move the
pick implementation and reactivity to the MetaSurfaceActor, and update
the code everywhere else to expect a MetaSurfaceActor.
I implemented pinging, but never actually enabled the feature
properly on Wayland surfaces by setting the net_wm_ping hint to
TRUE, causing the fallback path to always be hit.
Rename net_wm_ping to can_ping so it doesn't take on an
implementation-specific meaning, and set it for all Wayland windows.
I tested this with meta_window_get_input_rect and decided to change
it at the last minute. Turns out meta_window_get_rect is unlike all
the others. Just access window->rect directly instead.
Now that we call set_custom_frame_extents, the frame rect corresponds
to the "visible window geometry" used for constrainment, while the
x/y fields in get_xdg_popup instead are relative to the surface.
Something noticed on code inspection. If we have a popup grab,
it will always return FALSE. The code here clearly meant to continue
if we had an existing popup grab from an existing client.
Both the pointer/keyboard resource and surface resource can be destroyed
at any point in the destruction process, so we need to have destroy
listeners on both. To make the code easier to follow, rename ->focus
to ->focus_surface at the same time, and rearrange the code so that
the two of them are always grouped together.
To prevent the MetaSurfaceActor from being destroyed, we normally
unparent it before we unmanage the window. However, this doesn't
work for XWayland windows, which we unmanage when we get UnmapNotify
or DestroyNotify, not when we get the wl_surface_destroy.
To solve this, add an early hook in meta_window_unmanage that
unparents the surface actor if we have one. At the same time, clean
up the destruction code to remove old comments and assumptions about
how wl_shell behaves.
It doesn't work now that we set the pivot point. This breaks the
maximize effect, but it fixes the destroy effect. The maximize effect
looks bad anyway, so it's not too important to me.
