a4a688ed83 Rewrite background code
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.

711f0c0c50 common: Make UNKNOWN a flag, not a combination of all directions
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.

f42258327b util: Move the text direction stuff out of MetaUI

20a6243c85 Remove use of META_KEY_BINDING_REVERSES
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.

c5c6b2257f Add meta_key_binding_is_reversed()
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.

19795c1681 workspace: Add a "workspace-index" property to MetaWorkspace
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.

517e8f6fbd common: Create a better encoding for MetaGrabOp
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.

467465c99c backend: Create the stage in the backend, rather than the compositor
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.

3a57f843d5 Add a framework for restarting the compositor with nice visuals
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.

188e4e1b92 window: Rename get_input_rect to get_buffer_rect
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.

b64548ee1f Pass button_rect when opening window menu from button
When opening the window menu without an associated control - e.g.
by right-clicking the titlebar or by keyboard - using coordinates
for the menu position is appropriate. However when the menu is
associated with a window button, the expected behavior in the
shell can be implemented much easier with the full button geometry:
the menu will point to the center of the button's bottom edge
rather than align to the left/right side of the titlebar as it
does now, and the clickable area where a release event does not
dismiss the menu will match the actual clickable area in mutter.

So add an additional show_window_menu_for_rect() function and
use it when opening the menu from a button.

c2ea650b3c Add support for app-menu button in window decorations
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.

ebb6847bd1 ui: Don't use grab ops for grab negotation
Grab operations are now always taken on the backend connection, and
this breaks GTK+'s event handling.

Instead of taking a grab op, just do the handling ourselves. The
GTK+ connection will get an implicit grab, which means pointer /
keyboard events won't be sent to the rest of mutter, which is good.
