cebcc837de gl: add convenient functions to setup default vertex and fragment shaders
Most of our 2D filters use the same simple vertex shader.
Also define the default fragment shader as the identity.

Avoid duplicating the same vertex and fragment shader text.

d17a4381b1 [732/906] build: fix repeated typedefs
Write forward declarations in another way to avoid
repeated typedefs "error: redefinition of typedef".
Raised when using i686-apple-darwin11-llvm-gcc-4.2
It seems that C apple compiler does not support
C11 feature.

1a04002052 [681/906] win32: fix gl api calls on 32-bit
win has the bright idea of having 5 different calling conventions.
we should probably use the right one so we don't crash from stack
corruption.

f008fa71ab [467/906] tests: various build fixes
- cmake could not find glib
 - put gtk variables at the beginning to avoid GL conflicts
 - update examples to clutter-1.8
 - use const instead of deprecated G_CONST_RETURN
 - set max pending events to 0 to make cube example works again

b85ffef956 [387/906] glmixer: add a glmixer base element
glmixer can be seen as a glfilter except it handles N requested
sink pads.
Each sink pad and the src pad are video/x-raw-gl.
glmixer is responsible for managing different framerates from inputs.
It uses OpenGL context sharing. It means that each input is in its
own OpenGL context shared together and shared with the OpenGL context
of the ouput gl chain.
Also add a glmosaic which is an example of implementation of glmixer.
For now glmosaic is a cube but it will be fixed in the next commits.
For now the glmixer has some weird behaviours in some configurations
but it will be improved in the next commits.
The autotools builds is temporarly broken since those changes
have been made on win32.

61a8f34442 [321/906] add OpenGL ES 2.x support.
In OpenGL 2.x for Embedded System, a lot of basic scene/draw functions
have been removed. It means that everything is made using vertex and
fragment shaders.
I have also added a gstglwindow backend for winCE that uses EGL
(Native Platform Graphics Intercace) (which is a full part of
OpenGL ES specification). It remove the use of wgl/glx functions.

f0b62d760f [298/906] Revert "Fix indention"
This reverts commit 96e4ab18c2cf9876f6c031b9aba6282d0bd45a93.

You should have asked first.  And you would have been told "no",
because it causes people on development branches to do a huge
amount of extra work.
