Sophisticated clients, like those using ClutterGtk, will have more
than one focused resource per client, as both Clutter and GDK will
ask for a wl_pointer / wl_keyboard. Support this naturally using
the same "hack" as Weston: multiple resource lists, where we move
elements from one to the other.
In order to support multiple pointers for the same client, we're
going to need to kill it.
This will cause crashes for now, but will be fixed by the next
commit.
Doing this synchronously means that zenity tries to initialize GTK+.
Under Wayland, that will try to connect back to mutter as a display
server. We're waiting on zenity to exit, and zenity is waiting for
a connection response. Deadlock.
Simply assume that zenity will support all the options we feed it,
since it should be the correct version. Perhaps we should replace
our use of zenity with a simple helper binary that we know will
have all the right options if this still isn't good enough.
Our focus stealing prevention is still mostly inherited from metacity;
in particular, a (non-transient) window that is not on the current
workspace will not be given focus. This behavior made sense in the
GNOME 2 days, where workspaces were separated much more strictly.
However this is no longer the case in GNOME 3 - activating a launcher
will switch workspaces if necessary, and so will the app switcher.
There is no good reason to not do the same for other user actions
like clicking a URL or activating a search result, so allow activation
of windows on non-active workspaces if a proper timestamp is supplied,
assuming that this is a strong enough indication that we are dealing
with a legitimate user action.

Effectively we have been accepting CurrentTime timestamps for years,
but still complained about "stupid pagers" when encountering them;
just accept that we will never limit treating 0 timestamps as current
time to pagers.

The code that restacks X11 windows at the end first tracks any
old windows we know about, and then handles any windows created.
It starts when it ended, and then walks forwards and then
back looking for the first X11 window it doesn't know about.
However, when there aren't any X11 windows, it flies off the end
of the array and starts looking through random memory.
When it finds the X11 window, it then goes through and then tries
to restack the remaining windows according to how we've sorted
them.
Unfortunately, META_WINDOW_CLIENT_TYPE_X11 is 0, which is quite
common in random memory we have lying around, so we enter that
path and then just crash.
Fix the buffer overrun by adding the proper bounds check to the
search.
You can easily reproduce this by opening a menu while bloatpad
is full-screen. Why it only crashes when full-screen and not
when a standard window, I have no idea.
default_grab_focus tries to add implicit grab semantics where
focus won't take effect if there's a pointer button down. This
is not what we want for popup grabs at all, as it's perfectly
valid to want to drag on a menu while there's a button down.
The idea here is that while we take a WM-side grab, like a compositor
grab or a resizing grab, we need to remove the focus from the Wayland
client.
We make a special exception for CLICKING operations, because these
are really an internal state machine while you're pressing on a button
inside a frame, and in this case, we need to not kill the focus.
Really, it is a special case. When the subsurface is synchronous,
commit changes meaning from being applied immediately to being
queued up for replay later. Handle this explicit special case
with an explicit special case in the code.
This means that in all other paths, we can unconditionally
apply the actor immediately.
Even when it doesn't have a role.
This fixes cursors not quite working right, as they're a "detached"
surface without a role since nobody called set_cursor on them yet.
Instead of using commit_attached_buffer / actor_surface_commit.
We want to kill the return values of these methods because we
really should always be calling them, even if the surface doesn't
have a role.
This is also something that we did upstream. Since we want to
introduce an explicit "xdg_transient" window type for tooltips
and popovers, and since "transient_for" is a confusing dumb
80s term lifted from the ICCCM spec, just rename it.
This was changed upstream a little while ago for C++ compatibility.
It's also the more common term for the operation: you close a window,
you don't delete one. In fact, a delete event might seem like it
would be about resource management instead.
Except while reading _NET_WM_WINDOW_OPACITY, opacity is between 0 and 255. With
guint8, we'll get compiler warnings if arbitrary int values are passed.

This has one regression: the basic touch support added by
Carlos Garnacho in 991c85f is now partially reverted, since
we ported to Clutter events for this. We'll need to either
port his changes to Clutter, or restructure event handling
in mutter directly.
We can't really support the Gtk+ automatic scaling, as to much
code relies on the GdkWindow and XWindow sizes, etc to match.
In order to keep working we just disable the scaling, meaning
we will pick up the larger fonts, but nothing else. Its not
ideal but it works for now.
