For Wayland, we want to have everything possible in terms of the frame
rect, or "window geometry" as the Wayland protocol calls it, in order
to properly eliminate some flashing when changing states to fullscreen
or similar.
For this, we need to heavily refactor how the code is structured, and
make it so that meta_window_move_resize_internal is specified in terms
of the frame rect coordinate space, and transforming all entry points
to meta_window_move_resize_internal.
This is a big commit that's hard to tear apart. I tried to split it
as best I can, but there's still just a large amount of changes that
need to happen at once.
Expect some regressions from this. Sorry for any temporary regression
that this might cause.
We have two different coordinate spaces here. One is the rectangle
returned by meta_window_get_frame_rect, which is called the "frame
rect" or "the window geometry", which includes visible frame borders
but not invisible frame borders. The other is "frame->rect" which
corresponds to the frame's server geometry. That is, it includes
both visible and invisible frame borders.
These two were of course the same until we introduced invisible
frame borders, and an executive decision was made to make
meta_window_get_frame_rect return the rectangle bounding the
visible portions of the frame.
As time went on, the "frame rect" turned out to be more useful when
making decisions upon, since the user often doesn't think about the
invisible window geometry as part of the window.
We already calculate what amounts to the "frame rect" in the theme
code, so just change META_CORE_GET_FRAME_RECT to consume that
directly.
Since we're going to be calling meta_window_get_frame_rect in here
soon, I'd rather it be one method call, rather than two. We can't
put it at the toplevel, since that might cause infinite recursion
(e.g. meta_core_get calls meta_window_get_frame_rect calls
meta_ui_get_frame_borders calls meta_core_get, ...)
Now that meta_window_move_resize and friends act in frame rect
coordinates, we need to convert the initial grab_anchor_window_pos
storage to be in frame rect coordinates as well.
This makes Alt+F7 / Alt+F8 work respectively under X11 nested mode.
For the native backend implementation, we'll need a special Clutter
function, so don't implement that for now.
The last commit added support for the "appmenu" button in decorations,
but didn't actually implement it. Add a new MetaWindowMenuType parameter
to the show_window_menu () functions and use it to ask the compositor
to display the app menu when the new button is activated.

We want to synchronize the button layouts of our server side
decorations and GTK+'s client side ones. However each currently
may contain buttons not supported by the other, which makes this
unnecessarily tricky.
So add support for a new "appmenu" button in the layout, to display
the fallback app menu in the decorations.

meta_window_get_position() returns the client rect position, which
we then pass to meta_window_move_frame. Just use the existing frame
rect coordinates.
The requested_rect is a strange name for it, because it's not actually
the rect that the user or client requested all the time: in the case of
a simple move or a simple resize, we calculate some of the fields
ourselves.
To the MetaWindow subclass implementations, it just means "the rect
before we constrained it", so just use the name unconstrained_rect.
This also makes it match the name of the MetaWindow field.
It looks weird to have Alt+Space pop up under the cursor instead
of the top-left corner of the window, and the Wayland request will
pass through the coordinates as well.
Add it to the compositor interface, and extend the
_GTK_SHOW_WINDOW_MENU ClientMessage to support it as well.
On X, basing the check whether the pointer is on the window on
Clutter events does not work, as the relevant events are handled
by GDK instead.
So add an X-specific window_has_pointer() implementation to also
fix mouse mode when running as X compositor.

Using clutter_actor_has_pointer() to test whether the pointer is
on the window makes for clean and nice-looking code, but does not
work in practice - ClutterActor:has-pointer is not recursive, so
we miss when the pointer is on the associated surface actor rather
than the actor itself.
Instead, check whether the window actor contains the core pointer's
pointer actor, which actually works.

We already do it in the theme code, but not the actual WM code. Since
we include the left/right borders, it only seems fair to include the
bottom border.
This effectively makes it so that shading a window means that the
client window "slot" has 0 height.
Otherwise, the X server might read the backend's connection before
GTK+'s, meaning that it sees the XIGrabKeycode requests before the
CreateWindow.
This fixes keybindings on windows not working immediately.
Thanks to Rui Matos <tiagomatos@gmail.com> and

Realistically, the user rect contains the unconstrained window
rectangle coordinates that we want to be displaying, in case
something in the constraints change.
Rename it to the "unconstrained_rect", and change the code to always
save it, regardless of current state.
When metacity was originally being built, the purpose of the user
rect was a lot less clear. The code only saved it on user actions,
with various other calls to save_user_window_placement() and a force
mechanism sprinkled in to avoid windows being snapped back to odd
places when constraints changed.
This could lead to odd bugs. For instance, if the user uses some
extension which automatically tiles windows and didn't pass
user_action=TRUE, and then the struts changed, the window would be
placed back at the last place a user moved it to, rather than where
the window was tiled to.
The META_IS_USER_ACTION flag is still used in the constraints code
to determine whether we should allow shoving windows offscreen, so
we can't remove it completely, but we should think about splitting
out the constrainment policies it commands for a bit more
fine-grained control.

This uses David Herrmann's new logind sessions interface to retrieve
fds for input devices, rather than using a custom setuid helper to do
the management. This vastly simplifies the interface.
This requires systemd v210, at least.

When switching from the stage cursor to the native cursor, we
forgot to repaint the stage to get rid of the old cursor. Fix
this by having the abstract cursor renderer class track whether
we're using the backend, rather than doing chain-up shenanigans.
The default focus interface uses the button count to determine
whether we should update the pointer focused surface. When releasing
an implicit grab, we need to send the button release events to the
implicitly grabbed surface, so we can't reset the focus surface too
soon. We already explicitly set the focus at the end of implicit
grabs, so counting the buttons after is perfectly fine.
Now that we don't have to regrab to change the cursor, since it's
simply the cursor on the root window, all we have to do is update
the cursor on the screen.
We expect that meta_screen_set_cursor while grabbed will properly
set the cursor on the root window. Make sure this works by simply
always using the root cursor when we have an active grab.
If we send out a configure notify for a window and then have some
other kind of state change, we need to make sure that we continue
to send out that new size, rather than the last size the client
sent us a buffer for.
In particular, a client might give us a 250x250 buffer and then
immediately request fullscreen. We send out a configure for the
monitor size and a state that tells it it's full-screen, but then
it takes focus, and since the client hasn't sent us a buffer for
the new size, we tell it it's fullscreen at 250x250.
Fix this.
It isn't necessary. As an X11 compositor, we'll only see the event
if we have the grab on the window, anyway.
This was causing issues moving windows as a Wayland compositor.
When we're a Wayland compositor, we get all the events, no exceptions,
so we don't need to grab.
This was masking focusing and raising issues under nested that showed
up under native.
