The new tiling code, instead of based around "tiling states", is instead
based around constrained edges. This allows us to have windows that have
three constrained edges, but keep one free-floating, e.g. a window tiled
to the left has the left, top, and bottom edges constrained, but the
right edge can be left resizable.
This system also is easily extended to support corner tiling. We also,
using the new "size state" system, also keep normal, tiled, and
maximized sizes independently, allowing the maximize button to bounce
between maximized and tiled states without reverting to normal in
between. Dragging from the top will always restore the normal state,
though.

We have been ignoring those buttons since 3.16 after they had been
broken in the default theme for a couple of versions. As nobody
appears to miss them, it's time to remove them for good.
The elementary guys would like this as an API, and I don't see any
reason to refuse -- this is quite nice shadow painting code :)
For some reason, gobject-introspection can't seem to cope with
MetaWindowShape. I'll look into it a bit later, but for now, mark
the function it has trouble with as (skip).
A much less hacky version of maximize / unmaximize is reimplemented
in terms of this, but it could also eventually be used for fullscreen /
unfullscreen, and tile / untile.
The existing private get_monitor_neighbor() function returns a
MetaMonitorInfo, which is private as well. Add a public wrapper
that returns a monitor index instead, as we do for other public
monitor-related methods.

This just exposes the type and the singleton getter necessary to make
it available to introspection. We'll expose more functionality as it
becomes needed.

Rest in peace you magnificent format, love-child of arcane X11 drawing
API and markup craze, you will not be missed.
We do remember however the bravery of a many men and women, who fearlessly
descended into the guts of your intrinsics and turned ugliness into beauty;
their work will still be spoken of when you will long have been forgotten.

Although not strictly a window group... This ClutterActor is
meant to stay always on top, and only show non-reactive actors
created by Mutter itself. Two possible usecases for this layer
are DnD surfaces, and touch spots.
We might also want to move cursors out of an overlay in MetaStage
into here at some point.
Make the vignette options properties so they can be animated;
modify the function-call API for meta_background_actor_set_vignette()
to correspond more closely to the 3 properties.
https://bugzilla.gnome.org/show_bug.cgi?id=735637
The old requirement that multiple MetaBackgroundActor objects be
layered on top of each to produce blended backgrounds resulted in
extremely inefficient drawing since the entire framebuffer had
to be read and written multiple times.
* Replace the MetaBackground ClutterContent with a plain GObject
that serves to hold the background parameters and prerender
textures to be used to draw the background. It handles
colors, gradients, and blended images, but does not handle
vignetting
* Add vignetting to MetaBackgroundActor directly.
* Add MetaBackgroundImage and MetaBackgroundImageCache to allow
multiple MetaBackground objects to share the same images
By removing the usage of ClutterContent, the following optimizations
were easy to add:
Blending is turned off when the actor is fully opaque
Nearest-neighbour filtering is used when drawing 1:1
The GLSL vignette code is slightly improved to use a vertex shader
snippet for computing the texture coordinate => position in actor
mapping.

This was the original intention, but it was thought to be easier
to mark this as a combination of all directions. It turned out to
instead cause subtle bugs since code that blindly checked & DIR_WEST or
similar turned out to get it wrong when it was UNKNOWN, so just make
it an explicit flag.
This fixes the cursor appearing in the wrong place when starting a
keyboard resize.
Now that the internal mutter bindings and gnome-shell stopped using
META_KEY_BINDING_REVERSES, and after moving the 'adding shift reverses
the keybinding action' logic to gnome-control-center, we can remove
META_KEY_BINDING_REVERSES from mutter.
Plugin API is broken as this constant is removed from the exported
headers. ABI is broken as using this flag is now a noop.
https://bugzilla.gnome.org/show_bug.cgi?id=732385
MetaKeyBinding can be marked as being reversed
(META_KEY_BINDING_IS_REVERSED), but MetaKeyHandlerFunc callbacks
cannot check whether this flag was set or not on the MetaKeyBinding
which triggered the callback.

This will be used to replace some of the hooks that are used to call
into window.c, so that the workspace index property is properly kept up
to date.
We can't name the property "index" since it causes conflicts with the
meta_workspace_index method. This should really be called
meta_workspace_get_index, but oh well.
MetaGrabOp is painful and tedious to work with, because it's a
sequential series of values, meaning we have to use a giant unreadable
switch statement to figure out some basic things about the value.
To solve this, modify the encoding for MetaGrabOp and for the specific
window grab operations so that they're a set of bitflags that we can
easily check.
This allows creating the stage much earlier than it otherwise would have
been. Our initialization sequence has always been a bit haphazard, with
first the MetaBackend created, then the MetaDisplay, and inside of that,
the MetaScreen and MetaCompositor.
Refactor this out so that the MetaBackend creates the Clutter
stage. Besides the clarity of early initialization, we now have much
easier access to the stage, allowing us to use it for things such as
key focus and beyond.
This function tells the obvious on X11, and implements a similar mechanism
on wayland to determine the "pointer emulating" sequence, or one to stick
with when implementing single-touch behavior.

The current GNOME Shell Alt-F2 restart looks very messy and also
provides no indication to the user what is going on. We need to
restart the compositor to switch in and out of stereo mode, so
add a framework for doing this more cleanly:
Additions:
meta_restart(): restarts the compositor with a message
MetaDisplay::show-restart-message: signal the embedding
shell to show a message
MetaDisplay::restart: signal the embedding shell to restart
itself.
meta_is_restart(): indicates whether the current instance is a
restart so we can suppress login animations.
A helper program meta-restart-helper holds the composite overlay
window up during the restart to avoid visual artifacts.

With get_input_region existing, get_input_rect is a misnomer. Really,
it's about the geometry of the output surface, and it's only used that
way in the compositor code.
Way back when in GNOME 3.2, get_input_rect was added when we added
invisible borders. get_outer_rect was always synonymous with server-side
geometry of the toplevel. get_outer_rect was used for both user-side
policy (the "frame rect") and to get the geometry of the window.
Invisible borders were meant to extend the input region of the frame
window silently. Since most users of get_outer_rect cared about the
frame rect, we kept that the same and added a new method, get_input_rect
to get the full rect of the framed window with all invisible borders for
input kept on.
As time went on and CSD and Wayland became a reality, the relationship
between the server-side geometry and the "frame rect" became more
complicated, as can be evidenced by the recent commits. Since clients
don't tend to be framed anymore, they set their own input region.
get_buffer_rect is also sort of a poor name, since X11 doesn't really
have buffers, but we don't really have many other alternatives.
This doesn't change any of the code, nor the meaning. It will always
refer to the rectangle where the toplevel should be placed.
Avoid populating *_VERSION constants through cflags in pkg-config-file
which could be overridden by the project using it. Properly prefix the
defines with META_ to make gi-scanner happy.
