f037b28a7b gl: initialize output params to 0 before calling gl functions 
The client side API of the Chromium's GPU Process has asserts
in debug mode that check that output params are initialized to 0.

e1b077d6af glshader: attempt to detect the gles2 inside opengl3 case 
This is necessary to use gles2 shaders in a GL 3 core context on
OS X which fails without a proper #version being set on the shaders.

3d0bc93edc glshader: remove references to gl3 specific shaders 
We rely specifically on gles2 shaders being supported by the GL
implementation with GL3 core profile.

40a4530c5d glshader: prevent from getting attributes without vertex shader 
It doesn't make sense to query for vertex attributes without a vertex
shader. Moreover this is causing a crash on OSX.

f09272f434 gl: Add/Update more debug statements 
Where possible, use the _OBJECT variants in order to track better from
which object the debug statement is coming from

Define (and use) GST_CAT_DEFAULT where applicable

Use GST_PTR_FORMAT where applicable

64e5b5a203 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.

dd7e054e2c [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.

db7d436bd8 [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.

ec0bb66fe9 [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.

43e574aa8f [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.
