When dragging a window over a screen edge and dropping it there,
maximize it vertically and scale it horizontally to cover the
corresponding half of the current monitor.
Whenever a "hot area" which triggers this behavior is entered, an
indication of window's target size is displayed after a short delay
to avoid distraction when moving a window between monitors.

Add a preference /apps/mutter/general/attach_modal_dialogs. When true, instead
of having independent titlebars, modal dialogs appear attached to the titlebar
of the parent window and are moved together with the parent window.

Cleanly build with --warn-fatal. Implementation:
* Liberally apply (skip) where the API is clearly C only, e.g. uses
XLib. The theming code and MutterPlugin are skipped too.
* Add missing (transfer) and (element-type) annotations
For a few functions that had a comment, I turned it into gtk-doc, but
I didn't (with a few exceptions) try to write new documentation in
this pass.
Libmutter-private's preview-widget.h depends on region.h, so that one
needs to be installed as well in order to keep dependees build.

XDamageSubstract can create a BadDamage
(when the window goes away before XDamageSubstract is called)
and thus resulting into a crash.
Fix it by protecting the call with an error trap.

The gdk_window_get_background_pattern() function copied from GDK and
introduced in commit 0839c10 has a small syntax error and uses a private
API (_gdk_drawable_ref_cairo_surface()). This patch imports the missing
API and fixes the syntax error.

If the user just presses a modifier (e.g., shift) during Alt+Tab grab, we need
to keep the grab in place to allow the custom Alt+Tab handler to deal with what
might simply be a change of tabbing direction.

We don't get correct notifications for the ::cogl-texture property of
ClutterTexture in the case when we are unsetting the pixmap before calling
XFreePixmap. (This is because ClutterX11TexturePixmap is a hack on top
of ClutterTexture and we're a hack on top of that.) So we need to manually
clear everything out.
For consistency we also make sure that we drop all references to dead
textures:
- When the shape changes
- If the window pixmap texture changes without first being cleared
(this is not expected to happen)

This patch adds a check in event_callback () to check whether the
window is override-redirect or not, and avoids unnecessarily calling
meta_window_set_user_time () if it is.

Rather than trying to find out from Clutter whether mipmap generation
can be used together with texture_from_pixmap, just always assume
it can't and use the MutterTextureTower emulation code.
This fixes a problem with our previous hack for doing the query
no longer working. In the rare cases where mipmap generation
is supported, it is unlikely to produce significantly more efficient
or better looking results than the emulation. (In terms of efficiency,
we have better knowledge of when we need to update the lower mipmaps
and when we don't than CoglTexturePixmapX11.)
Some care is taken so mutter_shaped_texture_set_create_mipmaps() works
when changed on the fly and properly discards the old mipmap levels.
This isn't necesary currently, since it can only be controlled via
envvar, but is easier than future-proofing through documentation.

At least with the Mesa/DRI implementation of GLX, calling XFreePixmap()
on a pixmap before glxDestroyPixmap() on the corresponding GLX pixmap
causes an X error. To avoid triggering this with the new
ClutterTexturePixmapX11 code, we need to move our XFreePixmap after
unsetting the pixmap from the actor.

gdk_window_get_back_pixmap() and gdk_window_get_background() have
been removed/deprecated. Use gdk_window_get_background_pattern()
as replacement.

When we do pseudo-management on an override-redirect window, we have to be
careful to augment the existing event mask, not replace it, or
delivery of pointer events will be disrupted.
When we unmanage a window, we shouldn't try to unselect events at all,
since that will interfere with event selection done by GDK.

Starting with clutter 1.4 clutter / cogl only knows whether TFP is in use after
setting the pixmap, so doing the check before setting the pixmap will just
lead to a wrong message.

g-ir-scanner is currently buggy and confuses the Gdk.Rectangle alias
with MetaRectangle. Since this is moderately hard to fix in
gobject-introspection and the fix would conflict with in-progress
changes, work around by doing a 'sed job' on the generated Meta.gir.
https://bugzilla.gnome.org/show_bug.cgi?id=623639
Export a boxed type for MetaRectangle; this is mostly of interest
because GdkRectangle has been turned into a typedef for
cairo_rectangle_int_t which causes massive problems for using it from
gobject-introspection based language bindings.

In order to replace calls to deprecated GDK code, the current
development version of GTK+ is required. Add some basic compatibility
code to allow building mutter with GTK+ 2.18.

The current effect API passes an unnecessary list of windows to
switch_workspace() and forces a window to be passed in when killing
the switch_workspace() effect.
We can simplify the interface to correspond more closely to how
it is actually used and fix these problems:
Remove the actors parameter to plugin->switch_workspace
Remove the events parameter to plugin->kill_effect and rename it to kill_window_effects
Add plugin->kill_switch_workspace
Remove mutter_plugin_manager_kill_effect
Add mutter_plugin_manager_kill_window_effects
Add mutter_plugin_manager_kill_switch_workspace
Remove mutter_plugin_effect_completed
Add mutter_plugin_[minimize/map/destroy/maximize/unmaximize]_completed

A mismerge of the Metacity commit "4943d79 Prevent window self-maximisation"
caused the window's user set size and position to be saved *before*
actually resizing the window to the unmaximized position rather than after.
This meant that after unmaximization the window was in an inconsistent
state and anything that caused a resize to be queued (like a change in
window properties by the application) would cause it to pop back to
the maximized size and position.

It's useful for plugins to be able to easily detect whether
or not a window is from a remote host. Also, make use of this
in the window delete codepath, instead of looking up the hostname
each time.

While debugging a focus problem, I noticed that Mutter had exactly
the debug statements I wanted under the META_DEBUG_FOCUS topic.
However, calling meta_set_verbose (true) results in enormous amounts
of other messages, and it's inconvenient to filter after having
started mutter.
This patch allows one to call Meta.add_debug_topic(Meta.DebugTopic.FOCUS)
from a console, and get just what one wants.

In commit d34ae764769 I switched mutter-window to ask for Raw rectangles
from the X server. This avoided 2 non synchronous and 2 synchronous X
requests per window with damage, per frame; 2 (non-sync) to
create/destroy a temporary region to copy the damage region into, 1 to
request the server to copy the damage region into a our given region and
another to fetch that region back into the client. The problem with raw
events though is that it's possible to DOS the compositor with them.
Instead of receiving an event for every bit of damage this patch instead
asks the server to only report BoundingBox changes to the damage region.

This function returns xid of the WM leader window (as defined by the
_NET_SUPPORTING_WM_CHECK mechanism of EWMH). For use by plugins that wish to
attach custom properties to this window.

Changing the number of workspaces via an external pager relies on the gconf
key; if a plugin adds or removes workspaces on the fly, we can get into a
situation when the stale number stored by the preferences matches the new
number requested by the pager, in which case the pager request becomes a nop.
This commit ensures that when the meta_screen_append_new_workspace() or
meta_screen_remove_workspace() functions are called, the stored value is
updated accordingly.
