b977d75059 Fix disabling debugging
When --disable-debug is passed to the configure script it was actually
still defining COGL_ENABLE_DEBUG so very little would end up being
disabled. If COGL_ENABLE_DEBUG actually got defined it would also fail
to compile because _cogl_debug_instances and COGL_DEBUG_N_LONGS from
cogl-debug.h were only defined if debugging is enabled but they are
used regardless.

This patch also makes it so that the _COGL_RETURN_IF_FAIL family of
macros that are used when glib support is disabled are now disabled if
debugging is disabled. When the glib macros are used they are already
disabled because we additionally define G_DISABLE_CHECKS.

'COGL_HANDLE_DEBUG' has been removed from the list of defines passed
when debugging is enabled because CoglHandle has already been removed
and it is not used anywhere in the code.

10340a5495 Adds libcogl-gles2 frontend GLES2 api
This adds a library that can be used instead of libGLESv2.so to provide
symbols for the GLES 2.0 api. This can be used for convenience when
using the cogl_gles2_context_ api since you don't need to manually go
through a CoglGLES2Vtable when calling the gles2 api so it should be
easier to port existing gles2 code to integrate with Cogl.

-Create a pre-defined cogl/cogl-gl-header.h(.win32) that is to be used on
 any Windows builds, and adapt the MSVC build process to set up and use

-Fix up glib-mkenums code generation .bat file that is generated during

-Since cogl/cogl-defines.h now contain versionioning info, and it no longer
 directly includes the GL headers, update the pre-configured
 cogl-defines.h[.win32|.win32_SDL] and use autotools to fill in the
 versioning info during "make"/"make dist".
-Fix up cogl/cogl-pango.rc.in so that they reflect the cogl-2.x versioning
 stuff correctly and versioning info can be filled in correctly during
 "make"/"make dist"

68a6e82828 Add support for the WebOS version of SDL
The stock 1.2.x version of SDL only supports regular OpenGL. The
version on WebOS is specially patched to add some extra API to request
a GLES1 or GLES2 context. This patch adds a configure check to detect
when Cogl is being built with the patched version of SDL. In that case
it will additionally allow the gles1 and gles2 drivers and set the
right video mode attributes to get the corresponding context.

a9d1939425 configure: Fix the check for _Static_assert
The check for whether the compiler supports _Static_assert didn't work
properly because the AC_TRY_COMPILE function puts the source
definition in its own main function. The test therefore ends up
declaring a nested main function which GCC allows. If _Static_assert
isn't available then it just looks like an implicit declaration of a
function which only causes a warning in GCC so it would still compile.

This patch changes it to use AC_COMPILE_IFELSE instead. This macro
makes it possible to specify the complete source code so
_Static_assert can be called from the global scope. AC_LANG_PROGRAM is
used to generate the program. For extra aesthetics it now also
generates a 'checking for...' message while the script is running.

6400b455b8 Don't include any GL header from the public GL headers
This splits the GL header inclusion from cogl-defines.h into a
separate headear called cogl-gl-header.h which we will only include
internally. That way we don't leak GL declarations out of our public
headers. The texture functions that were using GLenum and GLuint in
the public header have now changed to just use unsigned int. Note
however that if an EGL winsys is enabled then it will still publicly
include an EGL header. This is a bit more awkward to fix because we
have public API which returns an EGLDisplay and we can't determine
what type that is.

There is also a conformance test which just verifies that no GL header
has been included while compiling. The test isn't added to
test-conform-main because it doesn't actually test anything at
runtime.

185630085c Add -Wmissing-declarations to maintainer flags and fix problems
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.

• cogl_quaternion_init_from_quaternion and init_from_matrix have been
  given declarations in cogl-quaternion.h

bbcbece6c9 tests: Improve thoroughness and reporting of make test
This patch reworks our conformance testing framework because it seems
that glib's gtesting framework isn't really well suited to our use case.
For example we weren't able to test windows builds given the way we
were using it and also for each test we'd like to repeat the test
with several different environments so we can test important driver and
feature combinations.

This patch instead switches away to a simplified but custom approach for
running our unit tests. We hope that having a more bespoke setup will
enable us to easily extend it to focus on the details important to us.

Notable changes with this new approach are:

We can now run 'make test' for our mingw windows builds.

We've got rid of all the test-*report* make rules and we're just left
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.

The combinations tested are:
- OpenGL Fixed Function
- OpenGL ARBfp
- OpenGL GLSL
- OpenGL No NPOT texture support
- OpenGLES 2.0
- OpenGLES 2.0 No NPOT texture support

7497475295 Add support for main loop integration
This adds two new functions:

void
cogl_poll_get_info (CoglContext *context,
                    CoglPollFD **poll_fds,
                    int *n_poll_fds,
                    gint64 *timeout);

void
cogl_poll_dispatch (CoglContext *context,
                    const CoglPollFD *poll_fds,
                    int n_poll_fds);

The application is expected to call the first function whenever it is
about to block to go idle, and the second function whenever it comes
out of idle. This gives Cogl winsys's the ability poll file
descriptors for events. For example when handing swap complete
notifications, it can report that it needs to block on a file
descriptor.

The two functions are backed by winsys virtual functions. There are
currently no implementations. The default handler for get_info just
reports no file descriptors and an infinite timeout.

b72f255c0a Start to reduce dependence on glib
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.

b5a7657076 Starts porting Cogl conformance tests from Clutter
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.

a53af153c3 egl-gdl: Correctly substitute COGL_CEX100_LIBGDL_PREFIX
We weren't defining CLUTTER_CEX100_LIBGDL_PREFIX in the configure.ac and
thus failing to compile when selecting the EGL/GDL winsys. Take the
opportunity to rename that to COGL_CEX100_LIBGDL_PREFIX
