5d702853b8 glx backend: Adds support for GLX_INTEL_swap_event
If your OpenGL driver supports GLX_INTEL_swap_event that means when
glXSwapBuffers is called it returns immediatly and an XEvent is sent when
the actual swap has finished.

Clutter can use the events that notify swap completion as a means to
throttle rendering in the master clock without blocking the CPU and so it
should help improve the performance of CPU bound applications.

43efab46bc Intial Re-layout of the Cogl source code and introduction of a Cogl Winsys
As part of an incremental process to have Cogl be a standalone project we
want to re-consider how we organise the Cogl source code.

Currently this is the structure I'm aiming for:
cogl/
    cogl/
	<put common source here>
	winsys/
	   cogl-glx.c
	   cogl-wgl.c
	driver/
	    gl/
	    gles/
	os/ ?
    utils/
	cogl-fixed
	cogl-matrix-stack?
        cogl-journal?
        cogl-primitives?
    pango/

The new winsys component is a starting point for migrating window system
code (i.e.  x11,glx,wgl,osx,egl etc) from Clutter to Cogl.

The utils/ and pango/ directories aren't added by this commit, but they are
noted because I plan to add them soon.

Overview of the planned structure:

* The winsys/ API is the API that binds OpenGL to a specific window system,
  be that X11 or win32 etc.  Example are glx, wgl and egl. Much of the logic
  under clutter/{glx,osx,win32 etc} should migrate here.

* Note there is also the idea of a winsys-base that may represent a window
  system for which there are multiple winsys APIs.  An example of this is
  x11, since glx and egl may both be used with x11.  (currently only Clutter
  has the idea of a winsys-base)

* The driver/ represents a specific varient of OpenGL. Currently we have "gl"
  representing OpenGL 1.4-2.1 (mostly fixed function) and "gles" representing
  GLES 1.1 (fixed funciton) and 2.0 (fully shader based)

* Everything under cogl/ should fundamentally be supporting access to the
  GPU.  Essentially Cogl's most basic requirement is to provide a nice GPU
  Graphics API and drawing a line between this and the utility functionality
  we add to support Clutter should help keep this lean and maintainable.

* Code under utils/ as suggested builds on cogl/ adding more convenient
  APIs or mechanism to optimize special cases. Broadly speaking you can
  compare cogl/ to OpenGL and utils/ to GLU.

* clutter/pango will be moved to clutter/cogl/pango

How some of the internal configure.ac/pkg-config terminology has changed:
backendextra -> CLUTTER_WINSYS_BASE # e.g. "x11"
backendextralib -> CLUTTER_WINSYS_BASE_LIB # e.g. "x11/libclutter-x11.la"
clutterbackend -> {CLUTTER,COGL}_WINSYS # e.g. "glx"
CLUTTER_FLAVOUR -> {CLUTTER,COGL}_WINSYS
clutterbackendlib -> CLUTTER_WINSYS_LIB
CLUTTER_COGL -> COGL_DRIVER # e.g. "gl"

Note: The CLUTTER_FLAVOUR and CLUTTER_COGL defines are kept for apps

As the first thing to take advantage of the new winsys component in Cogl;
cogl_get_proc_address() has been moved from cogl/{gl,gles}/cogl.c into
cogl/common/cogl.c and this common implementation first trys
_cogl_winsys_get_proc_address() but if that fails then it falls back to
gmodule.

ecfa0c4f92 [build] Split out the custom silent rules
The silent rules we use for custom targets should be moved into a
separate Makefile.am that gets included from all the others.

94b35a4a5e [build] GCC_FLAGS is no more, MAINTAINER_CFLAGS is the One.
CC_FLAGS was a left over from the 0.8.x age. Killed it and use the
newer MAINTAINER_CFLAGS variable instead.

Robert Bragg
169d472d17 Use $(MAINTAINER_CFLAGS) in clutter/{x11,glx}/Makefile.am
These makefile weren't resulting in the addition of the maintainer flags while
building clutter.

        Create a new X11 backend class of which EGL and GLX 'real' backends
        then subclass. Effectively shares all X11 code between both backends
        avoids code duplication and brings many missing features to EGL X
        backend. Requires some cleanup and testing. (#518)

        * clutter/cogl/gles/cogl.c: (cogl_color):
        Add define to use color4ub only if configure finds it.
        If not fall back to old code.

        * configure.ac:
        Drop support for vincent checks.
        Drop sdles backend.
        Specifically check for color4ub call.

        Add initial 'cogl' implementation. 'cogl' is a simple abstration
        layer over GL and GL/ES used by clutter internally. It should
        eventually allow clutter applications to be run on both GL and GL/ES
        with just a recompile as well as provide more debugging and potentially
        profiling information for GL and GL/ES usage.

        This commit contains the initial GL implementation.

Assorted build fixes to pass distcheck.

	* clutter/glx/Makefile.am: Install the clutter-glx.h header.

	* clutter/Makefile.am: Actually apply linker flags.

	* configure.ac: Use a more readable CLUTTER_API_VERSION instead
	of CLUTTER_MAJORMINOR; require gobject-2.0 with glib-2.0 >= 2.10,
	as we are using GObject and the slice allocator from glib 2.10.

	* clutter.pc.in: Add the apiversion variable.
