3115a61688 [cogl] Rework the GL-error-to-string conversion
The code for the conversion of the GL error enumeration code
into a string is not following the code style and conventions
we follow in Clutter and COGL.

The GE() macro is also using fprintf(stderr) directly instead
of using g_warning() -- which is redirectable to an alternative
logging system using the g_log* API.

e80fcbc298 [cogl-clip-stack] Support pushing rectangles onto the stack using window coords
Previously clipping could only be specified in object coordinates, now
rectangles can also be pushed in window coordinates.

Internally rectangles pushed this way are intersected and then clipped using
scissoring.  We also transparently try to convert rectangles pushed in
object coordinates into window coordinates as we anticipate the scissoring
path will be faster then the clip planes and undoubtably it will be faster
than using the stencil buffer.

f85377372c [cogl] Updates all file headers and removes lots of trailing white space
Adds missing notices, and ensures all the notices are consistent. The Cogl
blurb also now reads:

 * Cogl
 *
 * An object oriented GL/GLES Abstraction/Utility Layer

741c4bb5e9 [cogl] Adds a bitfield argument to cogl_clear for specifying which buffers to clear
Redundant clearing of depth and stencil buffers every render can be very
expensive, so cogl now gives control over which auxiliary buffers are
cleared.

Note: For now clutter continues to clear the color, depth and stencil buffer
each paint.

e4d3b0536f [gl/cogl.c] #include <gmodule.h> for OS X builds
In unifying the {gl,gles}/cogl.c code recently, moving most of the code into
common/cogl.c the gmodule.h include was also mistakenly moved.

Thanks to Felix Rabe for reporting this issue.

Note: I haven't tested this fix myself, as I'm not set up to be able to
build for OS X

8a1b4f8326 Unifies 90% of the code in {gl,gles}/cogl.c in common/cogl.c
This code keeps on diverging and we get bugs and fixes in one version but
not the other. This should make things a bit more maintainable.
