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
mentioned in the README. This patch also changes it to use
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.

• A similar fix has been done for G_GNUC_NULL_TERMINATED and

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.

This adds an alternate version of the SDL winsys using the SDL 2 API.
The two versions are mutually exclusive and share the same
CoglWinsysID. Version 2 of SDL fits a little bit better with Cogl
because it supports multiple windows and the video subsystem can be
initialised entirely independently of the rest of the subsystems.
The SDL2 winsys creates an invisible dummy window in order to bind the
GL context after creating the Cogl display. This is similar to how the
X11 winsys's work.
SDL2 seems to support compiling with support for both GL and GLES.
However there doesn't seem to be a way to select between the two
backends outside of SDL. In fact if you do compile them both in it
seems to break down because it will always try to use the window
system functions from the GLES backend because those are filled in
second in the vtable. However when creating the window it will always
prefer to use the GL function to choose a visual. This function gets
confused because the GL backend has not been initialised at that
point. The Cogl backend therefore just leaves it up to SDL to pick a
sensible backend. It will then verify that it picked a GL library
which matches the Cogl driver by checking the string from
glGetString(GL_VERSION).

This option to GCC makes it give a warning whenever a global function
is defined without a declaration. This should catch cases were we've
defined a function but forgot to put it in a header. In that case it
is either only used within one file so we should make it static or we
should declare it in a header.
The following changes where made to fix problems:
• Some functions were made static
• cogl-path.h (the one containing the 1.0 API) was split into two
files, one defining the functions and one defining the enums so that
cogl-path.c can include the enum and function declarations from the
2.0 API as well as the function declarations from the 1.0 API.
• cogl2-clip-state has been removed. This only had one experimental
function called cogl_clip_push_from_path but as this is unstable we
might as well remove it favour of the equivalent cogl_framebuffer_*
API.
• The GLX, SDL and WGL winsys's now have a private header to define
their get_vtable function instead of directly declaring in the C
file where it is called.
• All places that were calling COGL_OBJECT_DEFINE need to have the
cogl_is_whatever function declared so these have been added either
as a public function or in a private header.
• Some files that were not including the header containing their
function declarations have been fixed to do so.
• Any unused error quark functions have been removed. If we later want
them we should add them back one by one and add a declaration for
them in a header.
• _cogl_is_framebuffer has been renamed to cogl_is_framebuffer and
made a public function with a declaration in cogl-framebuffer.h
• Similarly for CoglOnscreen.
• cogl_vdraw_indexed_attributes is called
cogl_framebuffer_vdraw_indexed_attributes in the header. The
definition has been changed to match the header.
• cogl_index_buffer_allocate has been removed. This had no declaration
and I'm not sure what it's supposed to do.
• CoglJournal has been changed to use the internal CoglObject macro so
that it won't define an exported cogl_is_journal symbol.
• The _cogl_blah_pointer_from_handle functions have been removed.
CoglHandle isn't used much anymore anyway and in the few places
where it is used I think it's safe to just use the implicit cast
from void* to the right type.
• The test-utils.h header for the conformance tests explicitly
disables the -Wmissing-declaration option using a pragma because all
of the tests declare their main function without a header. Any
mistakes relating to missing declarations aren't really important
for the tests.

Notable changes with this new approach are:
We can now run 'make test' for our mingw windows builds.

with 'make test'
'make test' now runs each test several times with different driver and
feature combinations checking the result for each run. 'make test' will
then output a concise table of all of the results.

- OpenGL ARBfp
- OpenGL GLSL

descriptors for events. For example when handing swap complete

distribute cogl-enum-types.c, cogl-enum-types.h to ease compilation and
to avoid depending on PERL on Windows installations.
-Added rules in cogl-pango/Makefile.am to expand the cogl-pango VS2008/
2010 projects and filters from the templates with up-to-date source file
listings.
-Added/edited various Makefile.am's in build to distribute the VS2008/2010
project files and associated items required for the build.
-Update .gitignore. There needs to be a pre-configured
config.h(.win32) and its template, config.h.win32.in for Visual C++
builds

Since we've had several developers from admirable projects say they
would like to use Cogl but would really prefer not to pull in
gobject,gmodule and glib as extra dependencies we are investigating if
we can get to the point where glib is only an optional dependency.
Actually we feel like we only make minimal use of glib anyway, so it may
well be quite straightforward to achieve this.
This adds a --disable-glib configure option that can be used to disable
features that depend on glib.
Actually --disable-glib doesn't strictly disable glib at this point
because it's more helpful if cogl continues to build as we make
incremental progress towards this.
The first use of glib that this patch tackles is the use of
g_return_val_if_fail and g_return_if_fail which have been replaced with
equivalent _COGL_RETURN_VAL_IF_FAIL and _COGL_RETURN_IF_FAIL macros.

This namespaces all of the examples and marks them for installation
if --enable-examples-install has been passed to ./configure. This
simplifies packaging the examples which can be quite convenient
for smoke testing Cogl on various platform.

G_DISABLE_DEPRECATED is only intended for developers of Cogl and it
sometimes breaks the build for people just trying to build a
release. This patch adds an option to enable deprecated Glib
features. By default it is enabled for non-git versions of Cogl.
The patch is based on similar code in Clutter except it adds the flags
to COGL_EXTRA_CFLAGS instead of having a separate variable.

This splits out the core CoglPipelineLayer support code from
cogl-pipeline.c into cogl-pipeline-layer.c; it splits out the debugging
code for dumping a pipeline to a .dot file into cogl-pipeline-debug.c
and it splits the CoglPipelineNode support which is shared between
CoglPipeline and CoglPipelineLayer into cogl-node.c.
Note: cogl-pipeline-layer.c only contains the layer code directly
relating to CoglPipelineLayer objects; it does not contain any
_cogl_pipeline API relating to how CoglPipeline tracks and manipulates
layers.
This makes a start on porting the Cogl conformance tests that currently
still live in the Clutter repository to be standalone Cogl tests that no
longer require a ClutterStage.
The main thing is that this commit brings in is the basic testing
infrastructure we need, so now we can port more and more tests
incrementally.
Since the test suite wants a way to synchronize X requests/replies and
we can't simply call XSynchronize in the test-utils code before we know
if we are really running on X this adds a check for an environment
variable named "COGL_X11_SYNC" in cogl-xlib-renderer.c and if it's set
it forces XSynchronize (dpy, TRUE) to be called.
By default the conformance tests are run off screen. This makes the
tests run much faster and they also don't interfere with other work you
may want to do by constantly stealing focus. CoglOnscreen framebuffers
obviously don't get tested this way so it's important that the tests
also get run on screen every once in a while, especially if changes are
being made to CoglFramebuffer related code. On screen testing can be
enabled by setting COGL_TEST_ONSCREEN=1 in your environment.
Cogl requires gobject and gmodule API, so we need to check for these and
add them to the pkg-config files as dependencies, otherwise building
Cogl with --as-needed (like modern distributions now do) will cause
build errors.

Only cogl-pango needs a dependency on pangocairo so we are now careful to
separate the pangocairo pkg-config flags from the others so we can avoid
having libcogl builds refer to them.

It's not necessary to generate cogl-display.h just for the GDL backend
and to change the inclusion of libgdl.h. We can just tweak the include
CFLAGS to put /usr/include/CE4100 in the search path when needed.
Previously this did not work because of a stay ',' at the end of the
COGL_EXTRA_CFLAGS int he configure.ac. This actually simplifies the
code, which is always good.
This also fixes out of tree builds.

We weren't defining CLUTTER_CEX100_LIBGDL_PREFIX in the configure.ac and

AC_CHECK_HEADER(S) for eglext.h need include egl.h as it may not be done
for you.
The patch tries to integrate with the previous work to check if
GLES/egl.h ir EGL/egl.h should be included for egl.h.
This adds 3 configure options to override the library name that gets
dlopened for GL, GLES and GLESv2. This could be useful for distro
maintainers who have an unusual name for the libraries (for example,
on OpenBSD the GL library appears to be called libGL.so.4). This could
at least be simpler than having to create a distro patch.
The configure options would be used like this:
./configure --with-gl-libname=libGL.so \
--with-gles1-libname=libGLESv1.so \
--with-gles2-libname=libGLESv2.so
