For attached modal dialogs, we want the shadow to fade out at the top
as if the window was glued to the parent at the top. Add a
shadow-top-fade property to MetaWindowActor and the corresponding
parameter to meta_shadow_factory_get_shadow().
The internal implementation of MetaShadow is adjusted to work
in terms of an "inner border" and "outer border" instead of doing
the calculations in terms of an aggregate border and the spread
of the shadow. The old way of doing things gets clumsy when the
top_fade distance is added in as well.

The current shadow code just uses a single fixed texture (the Gaussian
blur of a rectangle with a fixed blur radius) for drawing all window
shadows. This patch adds the ability
* Implement efficient blurring of arbitrary regions by approximating
a Gaussian blur with multiple box blurs.
* Detect when multiple windows can use the same shadow texture by
converting their shape into a size-invariant MetaWindowShape.
* Add properties shadow-radius, shadow-x-offset, shadow-y-offset,
shadow-opacity to allow the shadow for a window to be configured.
* Add meta_window_actor_paint() and draw the shadow directly
from there rather than using a child actor.
* Remove TidyTextureFrame, which is no longer used

While the Meego developers agreed to switching mutter to GTK+-3.0
unconditionally a while ago, Canonical used a GTK+-2.0 build for their
Unity project. As Canonical now announced a switch to compiz as their
window manager, there is no longer a reason to maintain GTK+-2.0
compatibility.

Move all objects and functions namespaced with Mutter into the Meta namespace
to get a single consistent namespace. Changes that aren't simply changing mutter
to meta:
MutterWindow => MetaWindowActor
mutter_get_windows => meta_get_window_actors
mutter_plugin_get_windows => meta_plugin_get_window_actors
https://bugzilla.gnome.org/show_bug.cgi?id=628520
In many places, MetaRegion was being used entirely internally, rather
than for gtk2/gtk3 compatibility. In these cases, it's simpler to just
depend on cairo-1.10 (for both gtk2 and gtk3) and use cairo_region_t.
The few places where we did need GDK compatibility (GdkEvent.region and
gdk_window_shape_combine_mask) are replaced with a combination of
converting GdkRegion to cairo_region_t and conditional code.
https://bugzilla.gnome.org/show_bug.cgi?id=632474
Currently mutter-window has its own type field, even though the same
information is already present in meta_window.
And while at it get rid of MetaCompWindowType, it is equally redundant.
https://bugzilla.gnome.org/show_bug.cgi?id=630363
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.
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.

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)
https://bugzilla.gnome.org/show_bug.cgi?id=627210
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.
https://bugzilla.gnome.org/show_bug.cgi?id=627210
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.

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

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.

COGL bug http://bugzilla.openedhand.com/show_bug.cgi?id=2110 results
in pending drawing at the time of cogl_offscreen_new_to_texture() going
to the newly created framebuffer rather than the stage.
This would result in most windows being missing for the first frame
when a new window is mapped.
Work around this by calling cogl_flush() before
cogl_offscreen_new_to_texture().
https://bugzilla.gnome.org/show_bug.cgi?id=618138
The beginning maximization/unmaximization don't go through
start_effect_simple(), so we need to freeze the window
separately.
Change MutterWindow.freeze_count to a signed integer for
consistency with other counts, and so the logic for
checking for errors works properly.
https://bugzilla.gnome.org/show_bug.cgi?id=616546
This changes the way we handle Damage events so instead of getting an
event when the damage region of a pixmap becomes non-empty we now get
sent all damage rectangles and stream those all though to
ClutterX11TexturePixmap using clutter_x11_texture_pixmap_update_area()
For Clutter 1.2, ClutterGLXTexturePixmap was updated so that calls to
clutter_x11_texture_pixmap_update_area are now cheap (glXBindTexImageEXT
calls are now deferred until just before painting) and since
ClutterGLXTexturePixmap is now capable of queueing clipped redraws that
can result in only updating a sub-region of the stage during a repaint
cycle (and using glXCopySubBufferMESA to present the sub-region redraw
to the front buffer) this should improve performance and reduced power
consumption for a range of use cases. (For example viewing a website
that has animated adverts doesn't force the whole screen to be redrawn
for each frame of the advert)
Besides being able to take advantage of glXCopySubBuffer to only update
a small region of the stage the fact that this patch makes Mutter now
request RawRectangles from the X server means we no longer do a
synchronous X request for a complete Damage Region for every window
damaged each frame. This should also improve performance.
CLUTTER_PAINT=redraws can be used to visualize what parts of the stage
are redrawn and with this patch applied I can open a terminal and as I
type I see that only the damaged areas of the terminal are being
redrawn.
In the case where a mutter window is created for an X Window that is
already mapped then we weren't calling mutter_window_mark_for_repair and
so we weren't calling XCompositeNameWindowPixmap e.g. for menu windows.
This doesn't get noticed because as soon as some damage gets delivered
for such windows the pixmap will be named anyway, but if we were to
change how damage is handled this would result in broken menus.
We now call mutter_window_mark_for_repair in mutter_window_new when the
given Window is already mapped.
Although multi-screen support has not been tested and probably
doesn't fully work, the basic setup for multi-screen is that
we have the same list of plugins for all screens, but a different
instance of the plugins for each screen.
To allow plugins to do setup that is screen independent and needs
to occur early in the setup process, we identify a "default plugin
manager" and load (but not start) that plugin manager's plugins
immediately after we know our list of plugins.
That plugin manager is then reused for the first screen we open
and the plugins are started at that time. Separate plugin managers
are loaded and started for any other screens we open.
(A plugin could keep track of whether the screen-independent
setup has been done in a static variable, or it could do everything
in a way that is safe to do repeatedly.)
https://bugzilla.gnome.org/show_bug.cgi?id=615586
Rather than using the plugin objects constructed() method for doing
setup that requires the MetaScreen, add an explicit start() method
that is called after the screen is set.
The reason for this is that this allows plugin objects to be created
early before the bulk of Metacity setup, which then allows plugins
to affect how the setup happens. (For example, to change the way
that preferences are loaded.)
This is an incompatible change, since 'screen' is now not set in the
constructed method, so the plugin API version is bumped.
https://bugzilla.gnome.org/show_bug.cgi?id=615586
Since all windows are now MetaWindows as well as compositor
windows, there's no reason to keep a compositor-specific hash table
mapping from XID to MutterWindow.
This reduces complexity and removes a call to XQueryTree that could
potentially produce a BadWindow error if not error-trapped.
https://bugzilla.gnome.org/show_bug.cgi?id=613398
meta_compositor_process_event uses meta_error_trap_push/pop for
every event processed by meta_compositor_process_event which isn't needed
and can cause performance problems.

The older code relied on Clutter providing default texture coords for any
layers for which texture coords were not specified, which does not work as
of Clutter 1.1.6 (due to commit 8b950bdc87).

The CGL_* defines in COGL were always meant to be private and should
have never been exposed in the first place. The API in COGL has been
updated to never require them starting from 1.1, but using the original
GL symbols has always been the intent of the API.
This commit removes the CGL_TEXTURE_RECTANGLE_ARB usage in favour of the
ARB-sanctioned GL_TEXTURE_RECTANGLE_ARB enumeration value.

the identical PFNGLACTIVETEXTUREARBPROC instead.
the mutlitexture and texture_rectangle extensions have recently
been incorporated into the GL core; fixes needed to work with

Add MutterTextureTower, an abstraction for getting a image with
the right level of detail for rendering at a particular scale,
by manually scaling down by powers of two.
This results in much better looking scaled window images when
mipmaps can't be used with texture_from_pixmap (which is the
typical case for current GL drivers.)
When framebuffer objects are available, they are used to do
the scaledown using the GPU without having to pull the data
back from video memory. A software codepath is also available
for the case when FBO's are not present, though performance
will suffer

mutter_plugin_begin_modal() and mutter_plugin_begin_modal() allow putting
a plugin into a "modal" state. This means:
- The plugin has the keyboard and mouse grabbed
- All keyboard and mouse events go exclusively to the plugin

mutter-window.c originally grew an #include "window-private.h" for
window->override_redirect, but that was just fixed. However since
then it also ended up relying on a few other minor private bits.
To fix that, add meta_window_is_mapped, promote meta_window_toplevel_is_mapped
to public, and use the public MetaDisplay accessor.
