This splits out the cogl_path_ api into a separate cogl-path sub-library
like cogl-pango and cogl-gst. This enables developers to build Cogl with
this sub-library disabled if they don't need it which can be useful when
its important to keep the size of an application and its dependencies
down to a minimum. The functions cogl_framebuffer_{fill,stroke}_path
have been renamed to cogl_path_{fill,stroke}.
There were a few places in core cogl and cogl-gst that referenced the
CoglPath api and these have been decoupled by using the CoglPrimitive
api instead. In the case of cogl_framebuffer_push_path_clip() the core
clip stack no longer accepts path clips directly but it's now possible
to get a CoglPrimitive for the fill of a path and so the implementation
of cogl_framebuffer_push_path_clip() now lives in cogl-path and works as
a shim that first gets a CoglPrimitive and uses
cogl_framebuffer_push_primitive_clip instead.
We may want to consider renaming cogl_framebuffer_push_path_clip to
put it in the cogl_path_ namespace.

So as to avoid breaking the 1.x API or even the ABI since we are quite
late in the 1.16 development cycle the patch was modified to build
cogl-path as a noinst_LTLIBRARY before building cogl and link the code
directly into libcogl.so as it was previously. This way we can wait
until the start of the 1.18 cycle before splitting the code into a
separate libcogl-path.so.
This also adds shims for cogl_framebuffer_fill/stroke_path() to avoid
breaking the 1.x API/ABI.

You can pass arguments to gtkdoc-fixxref to point to other manuals,

The experimental HW decode path was adapted from clutter-gst based on
some experimental gstreamer api. This path was disabled by upstream
gstreamer developers back in september last year due to instabilities.
Without understanding how the experimental api is implemented it seems
rather strange to be plucking out the GL handle of a cogl texture and
passing that to some unknown gstreamer code which would presumably
somehow have to use the same GL context as Cogl to be able to do
something with that texture. For now we can strip all of this unused
code and it would be easy enough to re-instate later if it's useful.

CoglGst is a GStreamer integration library that facilitates
video playback using the Cogl API. It works by retrieving
each video frame from the GStreamer pipeline and attaching
it to a Cogl pipeline in the form of a Cogl texture along
with possible color model conversion shaders. The pipeline
is then retrieved by the user during each draw. An example
use of the CoglGst API is included in the examples directory.

This adds a white-box unit test that verifies that GL_BLEND is disabled
when drawing an opaque rectangle, enabled when drawing a transparent
rectangle and then disabled again when drawing a transparent rectangle
but with a blend string that effectively disables blending.
This shares the test utilities and launcher infrastructure we are using
for conformance tests so we get consistent reporting and so unit tests
will be run against a range of different drivers.
This adds a --enable-unit-tests configure option which is enabled by
default but if disabled will make all UNIT_TESTS() into static inline
functions that we should expect the compiler to discard since they won't
be referenced by anything.

This enables basic Emscripten support in Cogl via the SDL winsys.
Assuming you have setup an emscripten toolchain you can configure Cogl
like this:
emconfigure ./configure --enable-debug --enable-emscripten
Building the examples will build .html files that can be loaded directly
by a WebGL enabled browser.
Note: at this point the emscripten support has just barely been smoke
tested so it's expected that as we continue to build on this we will
learn about more things we need to change in Cogl to full support this
environment.

specify that we require at least version 1.0.0. This is now also

PKG_CHECK_MODULES instead of PKG_CHECK_EXISTS because it does need to

This updates Cogland example compositor to use the stable Wayland 1.0
API.
• When the client attaches a new buffer to a surface it is now added
to a struct contaning pending the state instead of immediately
switching to the new buffer. This state is then flushed when the
surface is committed.
• The frame callbacks are now queued in a pending list and only added
to the compositor's main list when the surface is committed. Both
lists are now a wl_list instead of a GQueue because it makes it
easier to remove the callback without knowing which list it is in.
• When the buffer is destroyed for a surface the resource for the
buffer is now sent a release event.
• It now flushes the clients in the prepare for the for the Wayland
event GSource. This is part of the multi-threaded API in this
Wayland patch:
http://cgit.freedesktop.org/wayland/wayland/commit/?id=53d24713a31d59
• Implements a dummy wl_region interface. The only interfaces that
actually use regions (the opaque and input regions) are ignored but
we need the interface to create a resource.
• Most the of the SHM interface is now implemented directly in
libwayland-server except that it still needs to copy the data to the
subregion of the texture when the damage region is committed.
• The callback list for when a resource is destroyed has been unified
into a generic wl_signal implementation so the signature for the
functions has been changed.
http://cgit.freedesktop.org/wayland/wayland/commit/?h=6802eaa68af9022
• The wl_buffer struct no longer has a user_data parameter so we can't
attach our own CoglandBuffer data to it. Instead the CoglandSurface
now just keeps track of the wl_buffer directly.
• The Cogland example is now unconditionally built instead of checking
the Wayland version number in the configure script. It looks like
this check was broken anyway because it was checking the version of
the gbm package rather than a Wayland package.

Some variables (notably multiline ones) are not really supposed to be

#define COGL_HAS_GTYPE_SUPPORT
#define COGL_HAS_GL
#define CLUTTER_COGL_HAS_GL
#define COGL_HAS_GLX_SUPPORT
#define COGL_HAS_SDL

This only works because the '#' character makes it look like a comment
and COGL_DEFINES becomes an empty variable
Automake allows to exclude variables from the list of substitutions,
let's use it for those two.

This fixes some problems which were stopping --disable-glib from
working properly:
• A lot of the public headers were including glib.h. This shouldn't be
necessary because the API doesn't expose any glib types. Otherwise
any apps would require glib in order to get the header.
• The public headers were using G_BEGIN_DECLS. There is now a
replacement macro called COGL_BEGIN_DECLS which is defined in
cogl-types.h.
• A similar fix has been done for G_GNUC_NULL_TERMINATED and
G_GNUC_DEPRECATED.
• The CFLAGS were not including $(builddir)/deps/glib which was
preventing it finding the generated glibconfig.h when building out
of tree.

The GDK pixbuf support requires being able to propagate errors from
GDKPixbuf as GErrors. This won't work if we are using the builtin
version of GLib because any attempt to call g_error_free from within
Cogl will use the internal version which will free the error using the
wrong slice allocator. It probably doesn't make much sense to build
without glib but with gdk-pixbuf so there's not much point in trying
to work around this situation.
Previously if you specified --enable-gdk-pixbuf but gdk-pixbuf was not
available it would silently disable it. This pach also fixes it so
that it will report an error in that case.
If --enable-gdk-pixbuf is not specified it will now default to
enabling it only if both glib is enabled and gdk-pixbuf is available.
This patch looks slightly longer than it ought to be because it moves
the check for glib up to above the descisions about the image backend.
