e8b83f2880 Adds wayland support to the cogl EGL winsys
Wayland now supports integration via standard eglSurfaces which makes it
possible to share more code with other EGL platforms. (though at some
point cogl-winsys-egl.c really needs to gain a more formal
CoglEGLPlatform abstraction so we can rein back on the amount of #ifdefs
we have.)

ef60979258 Adds experimental cogl 2.0 reference
This pulls in the experimental cogl 2.0 reference manual from the
clutter repository since it wasn't included in the filter-branch when we
split cogl out.

8d4a6f4d4c build: Enable building the documentation again
At least the 1.6.0 documentation. The 2.0 one has been missed by the
filter-branch and will be re-added later.

3919f3e97e configure.ac: Add the check for the ffs function
When Cogl was sharing Clutter's configure script, it had a check for
the ffs function of libc so that it can provide a fallback if it is
not available. This fallback was missed in the split out so Cogl would
end up always using the fallback.

8b4ee0964b Remove all the options for building cogl standalone
This removes all the remnants from being able to build Cogl standalone
while it was part of the Clutter repository. Now that Cogl has been
split out then standalone builds are the only option.

6f2193545e consistently refer to cogl-pango as "cogl-pango"
This renames the pango directory to cogl-pango and it renames the
installed library to libcogl-pango instead of libcoglpango.

fbda52d21b Give cogl-pango it's own pkg-config file
We now install cogl-pango-1.0 and cogl-pango-2.0 pkg-config files that
applications should optionally depend on if they want to use the
cogl_pango API.

4211462eb2 Make building cogl-pango optional
When building for platforms that don't use pango for handling text
you may not need the cogl-pango library.

d2e74d3a94 cogl/configure.ac: AC_SUBST an empty MAINTAINER_CFLAGS
For compatibility with the way we build Cogl as part of Clutter we now
substitute an empty MAINTAINER_CFLAGS variable. When building Cogl
standalone all our extra CFLAGS go through COGL_EXTRA_CFLAGS so the
separate MAINTAINER_CFLAGS aren't used, but automake will get confused
if a substitution isn't made.

a14e400dc9 cogl/configure.ac: check when building for win32
This adds a check for when building on win32 so we can skip pkg-config
checks for opengl and can add appropriate flags to
COGL_EXTRA_{LD,C}FLAGS.

e815928a5f cogl/configure.ac: fix pkg-config checks
This fixes the gdk-pixbuf check to not mistakenly check for the "xi"
package instead of gdk-pixbuf and remove a spurious listing "gl" in
COGL_PKG_REQUIRES which should only be there when we are using using
opengl not if we are using gles.

b3a7ee5930 cogl: remove OSX/WIN32 specific bits in favour of a stub winsys
Until Cogl gains native win32/OSX support this remove the osx and win32
winsys files and instead we'll just rely on the stub-winsys.c to handle
these platforms. Since the only thing the platform specific files were
providing anyway was a get_proc_address function; it was trivial to
simply update the clutter backend code to handle this directly for now.

0f7fce7e2b cogl/configure.ac: Adds --enable-stub-winsys option
We want to be able to split Cogl out as a standalone project but there
are still some window systems that aren't natively supported by Cogl.
This allows Clutter to support those window systems directly but still
work with a standalone Cogl library.

This also ensures we set the SUPPORT_STUB conditional in clutter's
configure.ac when building for win32/osx and wayland.

4bf868c0eb cogl/configure.ac: make COGL_HAS_xyz defines public
Instead of using AC_DEFINE for the various COGL_HAS_PLATFORM defines
this now adds them to the COGL_DEFINES_SYMBOLS variable which gets
substituted into the public cogl-defines.h header.

f5bb20212b Adds Cogl Hello World and "X11 foreign" example applications
This adds a simple standalone Cogl application that can be used to
smoke test a standalone build of Cogl without Clutter.

This also adds an x11-foreign app that shows how a toolkit can ask Cogl
to draw to an X Window that it owns instead of Cogl being responsible
for automatically creating and mapping an X Window for CoglOnscreen.

711d035f44 cogl/configure.ac: add options to control driver/egl platform
This allows more detailed control over the driver and winsys features
that Cogl should have. Cogl is designed so it can support multiple
window systems simultaneously so we have enable/disable options for
the drivers (gl vs gles1 vs gles2) and options for the individual window
systems; currently glx and egl. Egl is broken down into an option
for each platform.

7037812ae6 EGL: Updates GDL platform support
The GDL API is used for example on intel ce4100 (aka Sodaville) based
systems as a way to allocate memory that can be composited using the
platforms overlay hardware. This updates the Cogl EGL winsys and the
support in Clutter so we can continue to support these platforms.

8399f5e61c remove references to unused DRM_SURFACELESS EGL platform
The "DRM_SURFACELESS" EGL platform was invented when we were adding the
wayland backend to Clutter but in the end we added a dedicated backend
instead of extending the EGL backend so actually the platform name isn't
used.

1928f7ec0e backend: remove untested fruity backend
This backend hasn't been used for years now and so because it is
untested code and almost certainly doesn't work any more it would be a
burdon to continue trying to maintain it. Considering that we are now
looking at moving OpenGL window system integration code down from
Clutter backends into Cogl that will be easier if we don't have to
consider this backend.

efb570fdae Adds the ability to build Cogl standalone
This adds an autogen.sh, configure.ac and build/autotool files etc under
clutter/cogl and makes some corresponding Makefile.am changes that make
it possible to build and install Cogl as a standalone library.

Some notable things about this are:
A standalone installation of Cogl installs 3 pkg-config files;
cogl-1.0.pc, cogl-gl-1.0.pc and cogl-2.0.pc. The second is only for
compatibility with what clutter installed though I'm not sure that
anything uses it so maybe we could remove it. cogl-1.0.pc is what
Clutter would use if it were updated to build against a standalone cogl
library. cogl-2.0.pc is what you would use if you were writing a
standalone Cogl application.

A standalone installation results in two libraries currently, libcogl.so
and libcogl-pango.so. Notably we don't include a major number in the
sonames because libcogl supports two major API versions; 1.x as used by
Clutter and the experimental 2.x API for standalone applications.
Parallel installation of later versions e.g. 3.x and beyond will be
supportable either with new sonames or if we can maintain ABI then we'll
continue to share libcogl.so.

The headers are similarly not installed into a directory with a major
version number since the same headers are shared to export the 1.x and
2.x APIs (The only difference is that cogl-2.0.pc ensures that
-DCOGL_ENABLE_EXPERIMENTAL_2_0_API is used). Parallel installation of
later versions is not precluded though since we can either continue
sharing or later add a major version suffix.
