7ca28e0974 Add internal constructor function for each backend
We're going to use it to create an instance of each backend without
using the get_type() function.

This will allow clutter Wayland clients to either not draw any pointer

a5e44d3934 wayland: Add API for disabling the event dispatching
This allows the integration of Clutter with another library, like GTK+,
that is dispatching the events itself. This is implemented by calling
into the cogl_wayland_renderer_set_event_dispatch_enabled() and since
that function must be called on the newly created renderer the newly
added clutter_wayland_disable_event_retrieval must be called before
clutter_init()

78f20627ac wayland: Don't pass the shell and compositor down to Cogl
The Wayland 1.0 API allows orthoganal components of an application to
query the shell and compositor themselves by querying their own
wl_registry. The corresponding API in Cogl has been removed so Clutter
shouldn't call it anymore.

dfb145988e wayland: Only include Wayland headers in private
As wayland-client.h and wayland-server.h can't be included together,
split the Wayland backend file into clutter-backend-wayland.h, which
only defines the types, and clutter-backend-wayland-priv.h, which
actually uses the Wayland client types.

fce43c420e wayland: Use wl_cursor_theme to provide a buffer for the Wayland cursor
This change switches to the new mechanism for loading a cursor into a buffer.
It no longer relies on having a PNG stored in a known location and instead
loads from the Wayland cursor theme.

8f4e39b6d7 Port to new Wayland and xkbcommon APIs
For Wayland, this is mostly the input protocol having changed, although
there's also the SHM pool API, the cursor API, as well as fullscreen and
ping.

Also port to the new (months-old) xkbcommon API, as used by Weston 0.95.
This involves having xkbcommon manage the state for us, where
appropriate.  Fans of multi-layout keyboards (or just caps lock) will no
doubt appreciate these changes.

cf96c9caf3 include standalone cogl-wayland-server/client headers
Because the wayland-server-protocol.h header includes symbols that
collide with wayland-client-protocol.h Cogl now provides top level
<cogl/cogl-wayland-server.h> and <cogl/cogl-wayland-client.h> headers so
that applications can ensure they only include one of the wayland
protocol headers in a particular compilation unit. This updates clutter
accordingly to include those headers.

1f7968e5f9 wayland/x11: Set constraints on the CoglRenderer
When using the Wayland backend this sets a constraint that the
CoglRenderer selects the Wayland EGL winsys.

When a Wayland compositor display is set it now also sets a constraint
that the render should use EGL because only EGL renderers will set up
the required wl_drm global object.

The X11 backend now sets the X11 constraint.

e1434cebdb wayland: Load a buffer from well known location for the cursor
Semantic changes to Wayland means that we cannot rely on the compositor
setting a pointer buffer for us if set it to nil. The first part of fixing
this is to create an shm buffer containing the bytes for our cursor.

The best way to do this currently is to load the cursor from the well known
location where weston instals its cursor images. The code to implemente this
was derivedlifted from the Wayland backend in GTK+.

34cc45dae5 wayland: Update to latest Wayland API (wl_shell_surface transition)
Previously the wl_shell object held the methods that allowed a client to
request changes to the shell's state associated with a surface. These methods
have now been moved to a wl_shell_surface object.

This change allows configure events to be handled inside the stage rather than
the backend.

07c6f96cb4 wayland: Updates client side wayland support
This updates Wayland support in line with upstream changes to the Wayland
API and protocol.

This update means we no longer use the Cogl stub winsys so a lot of code
that had to manually interact with EGL and implement a swap_buffers
mechanism could be removed and instead we now depend on Cogl to handle
those things for us.

This update also adds an input device manager consistent with other
clutter backends.

Note: to use the client side "wayland" clutter backend you need to have
built Cogl with --enable-wayland-egl-platform. If Cogl has been built
with support for multiple winsys backends then you should run
applications with COGL_RENDERER=EGL in the environment.

adb6ffbd0e backend: Unify the event initialization
Input backends are, in some cases, independent from the windowing system
backends; we can initialize input handling using a model similar to what
we use for windowing backends, including an environment variable and
compile-/run-time checks.

This model allows us to remove the backend-specific init_events(), and
use a generic implementation directly inside the base ClutterBackend
class, thus further reducing the backend-specific code that every
platform has to implement.

This requires some minor surgery to every single backend, to make sure
that the function exposed to initialize the event loop is similar and
performs roughly the same operations.

a09bbffd92 Implement multi-backend support
The Clutter backend split is opaque enough that should allow us to just
build all possible backends inside the same shared object, and select
the wanted backend at initialization time.

This requires some work in the build system, as well as the
initialization code, to remove duplicate functions that might cause
conflicts at build and link time. We also need to defer all the checks
of the internal state of the platform-specific API to run-time type
checks.

09de87b0e5 backend: Remove atexit handlers
The g_atexit() function has been deprecated in GLib as it is a fairly
bad idea in basically all cases.

We could probably use a GCC destructor if we didn't care about
portability, but for the time being we just remove the atexit() handler
that disposed the backend.

532b563439 Add temporary cogl-clutter.h to aid splitting out Cogl
This gives us a way to clearly track the internal Cogl API that Clutter
depends on. The aim is to split Cogl out from Clutter into a standalone
3D graphics API and eventually we want to get rid of any private
interfaces for Clutter so its useful to have a handle on that task.
Actually it's not as bad as I was expecting though.

20b1350614 wayland: check for egl extensions explicitly
eglGetProcAddress() returns non-null function pointers
whether or not they're actually supported by the driver,
since it can be used before any driver gets loaded. So
we have to check if the extensions are advertised first,
which requires having an initialized display, so we split
the display creation code into its own function.

The exception to extension-checking is EGL_MESA_drm_display,
since by definition it's needed before any display is even
created.

134ce072e7 The amazing lazy-copy-back-repaint-page-flip
Always use pageflipping, but avoid full repaint by copying back dirty
regions from front to back.  Additionally, we dealy copying back until
we're ready to paint the new frame, so we can avoid copying areas that
will be repainted anyway.

This is the least amount of copying per frame we can get away with at all
and at the same time we don't have to worry about stalling the GPU on
synchronized blits since we always pageflip.
