ad707be01e window-actor: Add "size-changed" signal
Emit a signal when the window size changes. While it is already
possible to connect to notify::allocation (or width/height), the
new signal is emitted outside a clutter allocation cycle, which
makes it more convenient when adjusting an actor's size/position
in response.

8817e68926 Use COGL_MATERIAL_WRAP_MODE_* defines not COGL_PIPELINE_*
Since we aren't depending on Clutter 1.5 or using the new
CoglPipeline name elsewhere, we need to stick to the old
COGL_MATERIAL_WRAP_MODE_* names, which are provided with
compatibility defines in Clutter 1.4.

6260814285 Turn off background repeats for a full-size image
If we have repeats on for a full-sized image, then if the background
is displayed scaled (for example, in a desktop preview mode) then we
can get artifacts along the edge of the background where the repeat
of the opposite edge is blended in by bilinear scaling. So turn off
repeats when the screen and background image sizes match.

07e6c5aac2 Draw the root window background
Add code to track and draw the root window background. The advantage of doing
it here as compared to in a plugin is that we can use the visiblity smarts
of MetaWindowGroup to optimize out drawing the background when obscured.

If handling other than tracking the _XROOTPMAP_ID property is desired in the
future, more functionality like setting the background from a file or doing
cross-fades can be added.

The new background actor is exposed to plugins via meta_plugin_get_background_actor()
similar to other exposed actors to allow cloning the background for use in
other displays. The actual class is not installed for public consumption at
the moment since it has no useful methods.

bac668d287 Optimize out restacks that don't change actor order
For various reasons (mostly the stack tracker correctly predicting the
stacking order before getting events, but also because of the processing
that the compositor does to get the actor stacking order) the compositor
can be told to sync the stack when it has nothing to do. Detect this
at the last moment before actually telling Clutter to restack to avoid
triggering unnecessary redraws.

8b24711bba Omit shadows for fullscreen and maximized windows
Fullscreen and maximized windows never have visible shadows - the only
case where we would ever see them is if they bleed onto an adjacent
monitor and that looks bad.

It's small performance win to avoid computing them, and this also avoids
painting the top shadow for all maximized windows in GNOME Shell - since
the top panel isn't a X window, it doesn't factor into the computation
of what parts of windows are visible and maximized windows are computed
as having a top shadow.

1bbaec81ce Make window shadows globally configurable
Instead of setting shadow parameters on individual windows, add the
idea of a "shadow class". Windows have default shadow classes based
on their frame and window type, which can be overriden by setting
the shadow-class property.

Each shadow class has separably configurable parameters for the
focused and unfocused state. New shadow classes can be defined with
arbitrary names.

8eb31944a5 MetaShadowFactory: Add the ability to top-fade a shadow
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.

9f4942e9a7 Make shadows pretty and configurable
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

804117c456 Remove MetaRegion
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.

8b34b4bd0b MutterShapedWindow: drop all indirect references to textures
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)

c9ebc0ea25 Always use mipmap emulation
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.

91d82bf8c7 mutter-window: request DamageReportBoundingBox report level
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.

0c14640352 mutter-window: stream raw updates to ClutterX11TexturePixmap
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.

cfa30f9876 make sure we create a pixmap for all new mutter windows
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.
