Don't create the Cogl GLib source multiple times

Since the check for backend->cogl_context was accidentally moved
to clutter_backend_do_real_create_context, the Glib source that
is created at the end of clutter_backend_do_create_context() is
created and added each time create_context() is called, though
create_context() is supposed to be idempotent.

Allow setting up quad-buffer stereo output

Add clutter_x11_set_use_stereo_stage() that can be called
before clutter_init() so that the CoglDisplay we create and all
stages created from that CoglDisplay will be created with a
stereo fbconfig.

This is done in clutter-x11 because of the similarity to the
existing clutter_x11_set_use_argb_visual(), and because it's
not clear without other examples whether the need to have
stereo enabled from before clutter_init() is universal or
somethign specific to GLX.

ClutterEvent: add API to query the full keyboard state when the event was generated

When talking to other applications or serializing the modifier
state (and in particular when implementing a wayland compositor),
the effective modifier state alone is not sufficient, one needs
to know the base, latched and locked modifiers.

Previously one could do with backend specific functionality
such as clutter_device_manager_evdev_get_xkb_state(), but the
problem is that the internal data structures are updated as
soon as the events are fetched from the upstream source, but
the events are reported to the application some time later,
and thus the two can get out of sync.
This way, on the other hand, the information is cached in the
event, and provided to the application with the value that
was current when the event was generated.

Add clutter_stage_set_sync_delay()

New experimental API is added to allow changing the way that redraws
are timed for a stage to include a "sync delay" - a period after
the vertical blanking period where Clutter simply waits for updates.

In detail, the algorithm is that when the master clock is restarted
after drawing a frame (in the case where there are timelines running)
or started fresh in response to a queued redraw or relayout, the
start is scheduled at the next sync point (sync_delay ms after the
predicted vblank period) rather than done immediately.

actor: Add ClutterActorClass.layout_children()

The allocate() virtual is far too complex, and it has far too many
things that can possibly go wrong:

  - it needs to be chained up, to store the allocation of the actor;
    - unless you call set_allocation() to do that;
  - you can override it;
    - but you can also have a layout manager delegate;
  - you have to allocate() all the children after you chained up;
  - you may get signals mid-way through the allocation process;
  - you get a non-normalized box;
    - unless you're using a layout manager, which will get a
      normalized one.

Let's try to keep this stuff simple, and minimize the amount of things
to remember to get it right.

First of all, we add a new virtual, called layout_children(); it gets
passed the actor itself, and it will be called only if the actor has
children to lay out. Its default implementation will call the layout
manager's allocation method, if one is set. Inside the layout_children()
virtual, you will need to iterate over the children, compute their
bounds and call clutter_actor_allocate(), similarly to how you implement
a paint() virtual. The layout_children() virtual is called after the
allocation of the actor has been stored, so it's possible to safely
query it without hitting slow code paths. You do not need to chain up,
and you do not need to normalize boxes. All the signals and property
notifications on the parent will happen before the layout_children()
virtual has been called, so the actor's state is stable by the time you
call allocate() on the children.

blur-effect: Use a gaussian blur

This replaces the 3x3 box blur of ClutterBlurEffect with a two-pass
gaussian blur. The sigma value for the gaussian function (ie, the
bluriness) can be adjusted with a property. The radius for sampling is
limited to ⌈6σ⌉×⌈6σ⌉ as suggested by Wikipedia. The factors for the
sampling are stored in an array in a uniform so the effect only needs
to switch shaders when the sigma jumps to the next radius size. This
makes it feasible to animate the bluriness without depending on
conditional jumps in the shader.

The effect creates a second texture at the same size as the
offscreen's texture to implement the second pass. The effect avoids
redrawing the first pass if the actor is redrawn without being
dirtied. However if the sigma value changes it does need to redraw
both passes but it can still avoid repainting the actual actor.

The two passes share a single shader program with a uniform to
change the direction. The pipelines for each radius are cached in a
hash table attached to the class struct so they can be shared across
multiple instances of the effect.

Adds initial support for stereoscopic rendering

This adds initial support for stereoscopic rendering of Clutter scenes.
The major change here is that we've introduce the internal concept of a
ClutterCamera which encapsulates a viewport, projection and view
transform. In the future the camera will also encapsulate a reference to
the destination framebuffer, but for now it's assumed that the backend
framebuffer behind stage->priv->impl is associated with all cameras.

If clutter_stage_set_stereo_enabled (stage, TRUE) is called then Clutter
will now enable stereographic rendering, using a simple toe-in approach
of modifying the view transform for each eye to model that there is a
gap between the eyes and both eyes look towards the center of the z=0
plane (This is the plane where most 2d content for a clutter application
goes)

A notable disadvantage to the simple toe-in approach is that 2D content
on the z=0 plane will look different for each eye so straight lines
for example wont appear straight to the user. A better approach we will
implement later is to setup asymetric projections for each eye that
can model the eye gap but the frustums cross at the z=0 plane such that
both eyes would have the same view of 2D content.

Currently there are three modes of output for stereoscopic content.
 » There is anaglyph rendering (for use with filter glasses with a red
   filter for the left eye and cyan filter for the right)
 » There is a vertical split mode which splits the stage and shows the
   left eye content on the left and the right eye on the right.
 » There is a horizontal split mode which splits the stage and shows
   the left eye content on the top and right eye on the bottom.

The mode can be selected using clutter_stage_set_stereo_mode().

The mode can also be explicitly overridden using the CLUTTER_STEREO_MODE
environment variable by setting it to "default", "anaglyph",
"vertical-split" or "horizontal-split". Setting this environment
variable also implicitly forces stereo rendering to be enabled.

Support clipped redraws with flipping

This adds support for doing incremental, clipped redraws but also using
flipping to present instead of blitting.

The approach builds on Cogl's support for cogl_onscreen_start_frame(),
cogl_onscreen_get_back_buffer_age() and
cogl_onscreen_swap_buffers_with_damage().

At the start of each frame we determine how old the back buffer contents
are and if it's a reused buffer we aim to repair the old buffer based on
the history of regions that have changed since the old buffer was
created. When we present we present the back buffer we use
cogl_onscreen_swap_buffers_with_damage() which the driver can implement
using a flip and the damage region can also be passed to a system
compositor to ensure it only recomposes the region that changed.

cogl-pango-display-list: Use cogl_rectangles_with_texture_coords

Instead of storing four vertices per rectangle in the array for a
texture node in the display list, it now only stores two in a format
that is acceptable to cogl_rectangles_with_texture_coords. That way
it can pass the array directly to that function. That function has the
advantage over cogl_rectangle that it doesn't need to validate the
pipeline for every quad so it should be slightly faster.

When the texture node is being rendered with a CoglPrimitive we now
map the buffer and expand the rectangles into 4 vertices as the data
is copied.

experimental clipped redraws without extension

This implements an experimental approach to supporting clipped redraws
without the aid of an extension. Instead it depends on making an
assumption about the number of back buffers provided by the driver.

To tell Clutter about the number of back buffers set
CLUTTER_SWAP_CHAIN_LENGTH=3 for example in your environment before
running a Clutter app.

Note: This is unlikely to be big win if your driver doesn't actually
support flipping back buffers and instead uses a blit to present.

Compared to the blit based clipped redraw path we have when using GLX
one significant issue is that the whole window will effectively be
damaged when using glXSwapBuffers which means the whole window could
end up being blitted if the window isn't fullscreen. Even when
compositing, because we don't have a way to report a limited damage
region the compositor will be told that the whole window has been
damage.
