The Wayland backend is based on Cogl, so we need to turn on the
SUPPORT_COGL flag to avoid breaking the build; this always went
unnoticed because we usually build the Wayland client backend
with the X11 backend.

Not every single one, but things that we care about to avoid breaking
build on other platforms, or for security issues, should not be allowed.
We should not force everyone to use -Werror, though; and we should still
allow building Clutter without any special flag.
Unlike gcov, lcov provides a nice HTML output that allows immediate
visualization of the current coverage.
The updates of the build system have been taken from GLib, which has
been using lcov for a while with good results.
For now, it just generates a simple horizontal slide (by writing
to /dev/uinput) and checks that the stage gets the events at the
expected coordinates.
The test won't run if it doesn't have read/write permissions to
/dev/uinput.
It also adds OS_LINUX to config.h.
This should allow nicer build automation and cross-compilation support.
The former --disable-conformance configure switch has been deprecated by
the --disable-tests one, which is more encompassing as it disables the
whole test suite.
The example code that is meant to be XIncluded into the API reference
should not be part of the interactive test suite: it's code that it is
meant to be used as a reference implementation - whereas the interactive
test suite should be allowed to be lean and test behaviour even in nasty
ways. In short: the test suite should not be the place where we show off
idiomatic code for educational purposes.
configure.ac defines XINPUT_2_2 if XI 2.2 support was found. The code
expects XINPUT_2_2 in the device manager, but HAVE_XINPUT_2_2 in the x11
backend.
On newer X servers, the latter causes a BadValue when XIQueryDevice sends a
different major/minor than gdk's device manager (gnome-control-center).

The disjunction operator was misspelt as -O which tests whether the
following file is owned by the calling user. This doesn't take enough
arguments so bash was showing an error and the test was always
failing. This meant that NEED_XKB_UTILS was always false which should
have broken the build but the Makefile was mistakenly including
clutter-xkb-utils.c again if SUPPORT_WAYLAND is defined.
See 1b77565e for reference.

This adds a NEEDS_XKB_UTILS automake conditional that's set to true if
either the wayland backend is enabled or the evdev input backend is
enabled since they both depend on clutter-xkb-utils.c and we need
to avoid listing the file twice since that leads to duplicate symbols
and the build fails.

Some of Cogl's experimental apis have changed so that the buffer apis
now need to be passed a context argument and some drawing apis have been
replaced with cogl_framebuffer_ drawing apis that take explicit
framebuffer and pipeline arguments.
These changes were made as part of Cogl moving towards a more stateless
api that doesn't rely on a global context.
This patch updates Clutter to work with the latest Cogl api and bumps
the required Cogl version to 1.9.5.

GLib has gained support for compiling ancillary data files into the same
binary blob as a library or as an executable.
We should add this feature to ClutterScript, so that it's possible to
bundle UI definitions with an application.
If we go through the whole exercise of having private dependencies, we
should at least use the compiler flags and linker flags that those
dependencies give us when building Clutter.

When clutter has been built with Wayland compositor support then we now

This updates the evdev input backend code to compile and also updates
the code to not refer to the default stage and instead check for a
stage to be associated with the input device. If no stage is currently
associated with a device generating events then the events are dropped
on the floor.

This adds a --enable-wayland-compositor configure option which will add
support for a ClutterWaylandSurface actor which can be used to aid in
writing Wayland compositors using Clutter by providing a ClutterActor to
represent Wayland client surfaces.
Notably this configure option isn't tied into any particular backend
since conceptually the compositor support can be used in conjunction
with any clutter backend that has corresponding Cogl 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.

Instead of piggybacking on the EGL backend, let's create a small
ClutterBackend for the CEx100 platforms. This allows us to handle the
CEx100-specific details in a much cleaner way.
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.
Delimit the points in the configure script that should save the state,
so that running the script multiple times doesn't require starting from
scratch even if it didn't terminate successfully.
The event handling through tslib hasn't been tested in a while, and it
hasn't been ported to the device manager machinery either. We are still
considering whether or not it should be entirely removed, since evdev is
supposed to be a better way to handle events not coming from an existing
windowing system.
Instead of defining new symbols for the windowing systems enabled at
configure time, we can reuse the same symbols for both the compile time
and run time checks, e.g.:
#ifdef CLUTTER_WINDOWING_X11
if (clutter_check_windowing_backend (CLUTTER_WINDOWING_X11))
/* use the clutter_x11_* API */
else
#endif
#ifdef CLUTTER_WINDOWING_WIN32
if (clutter_check_windowing_backend (CLUTTER_WINDOWING_WIN32))
/* use the clutter_win32_* API */
#endif
This scheme allows us to ensure that the input system namespace is free
for us to use and select at run time in later versions of Clutter.
Perform the check for enabling platform-specific backends conditionally
on the 'check' value, instead of unconditionally.
Also, rename the configure switches for the backends to have a '-backend'
suffix, to avoid collisions and provide a more descriptive name.
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.
Previously, the Cogl backend was at times a subclass of the X11
backend, and at times a standalone one. Now it is the other way
round, with GDK and X11 backends providing the concrete classes,
layered on top of the generic Cogl backend. A new EglNative backend
was introduced for direct to framebuffer rendering. This greatly
simplifies the API design (at the expense of some casts needed)
and reduces the amount of #ifdefs, without duplicating code.

This commit introduces a new flavour for Clutter, that uses GDK
for handling all window system specific interactions (except for
creating the cogl context, as cogl does not know about GDK), including
in particular events. This is not compatible with the X11 (glx)
flavour, and this is reflected by the different soname (libclutter-gdk-1.0.so),
as all X11 specific functions and classes are not available. If you
wish to be compatible, you should check for CLUTTER_WINDOWING_X11.
Other than that, this backend should be on feature parity with X11,
including XInput 2, XSettings and EMWH (with much, much less code)
https://bugzilla.gnome.org/show_bug.cgi?id=657434
Since the image backend is something now dealt with by Cogl there is no
need to check the experimental status of the backend in the Clutter
configure script.

GLX is now totally abstracted by Cogl so the "glx" flavour is actually
only used to determine the soname of clutter now so we don't actually
have to check for the glx header or that libGL provides any GLX symbols.

Just like we turn everything on with --disable-deprecated, we have to
turn everything off with --enable-deprecated. This means disabling the
deprecation warnings from the compiler as well.
All 2D coordinate spaces in Cogl have their origin at the top-left so we
shouldn't be flipping the coordinates we pass to
cogl_framebuffer_swap_region to be relative to the bottom of the
framebuffer.
This bumps the Cogl version requirement to 1.7.5 since we've had to fix
a bug in the semantics of cogl_framebuffer_swap_region.

Clutter may be used together with GTK+, which indirectly may use
XInput2 too, so the cookie data must persist when both are handling
events.
What happens now in a nutshell is, Clutter is only guaranteed to allocate
the cookie itself after XNextEvent(), and only frees the cookie if its
XGetEventData() call allocated the cookie data.
The X[Get|Free]EventData() calls happen now in clutter-event-x11.c as
hypothetically different event translators could also handle other set
of X Generic Events, or other libraries handling events for that matter.
If we're building on/for Windows, set 'win32' as the default flavour; if
we're building on OS X, set 'osx' as the default flavour. For everything
else, use 'glx'.
