7c79b33108 gstglshader: cache uniform locations
Avoid redundant calls to glGetUniformLocation. The results can be cached once
the shader has been linked.

babd066b89 glshader: don't read invalid list pointers (use after free)
gst_gl_shader_detach_unlocked already removes the list entry so attempting to
use the element to iterate to the next stage could read invalid data.

Based on patch by Vineeth TM <vineeth.tm@samsung.com>

f24e768cc3 glshader: properly unref the stages on failure
When failing in the varargs functions, all the stage objects not handled need to
be unreffed to prevent a leak.

b25807c382 glshader: port to using GstGLSLStage objects for string management
A GstGLShader is now simply a collection of stages that are
compiled and linked together into a program.  The uniform/attribute
interface has remained the same.

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.

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.

64e5b5a203 gl: add convenient functions to setup default vertex and fragment shaders

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.
