dc02d47092 glbasebuffer: remove unsed memory subclass 
The functionality has been split into GstGLBaseMemory and GstGLBuffer.

76a38dd66a glmemory: base classify and add the pbo memory on top 
The base class is useful for having multiple backing memory types other
than the default.  e.g. IOSurface, EGLImage, dmabuf?

The PBO transfer logic is now inside GstGLMemoryPBO which uses GstGLBuffer
to manage the PBO memory.

This also moves the format utility functions into their own file.

5ab3a38973 gl: add a GL buffer based GstMemory 
Heavily based on GstGLBaseBuffer that is a subclass of GstGLBaseMemory.
Provides GPU and CPU accessible GL buffer objects by GL handle or by
sysmem data pointer.

af7015602a gl: add a base memory object 
It handles the following
- GstAllocationParams -> gst_memory_init transformation
- Makes sure that map/unmap/create/destroy happen on the GL thread with
  a GL context current.
- Holds a possible sysmem accessible data pointer with alignment.
- Holds the need upload/download transfer state

cd584d215c gluploadmeta; remove convenience helper API 
It was not really useful as if one knows about libgstgl, one can just use
GLMemory objects directly.

3545d340b6 gldownload: remove helper api from the library 
It was never used by anyone and is not needed anymore with the element
and GstGLMemory's transparent support for downloading textures.

33f73b400d glbufferpool: move typedef's into the forward decleration file 
Otherwise, for example, clang will warn about typedef redefinitions
being a C11 feature.

pipeline.

This object is only used inside the compositor and does not
need to be expose in libgstgl API.

279c2b07b4 glcompositionoverlay: Add class for managing GstVideoOverlayCompositionOverlay buffers 
Add a class to store and manage the OpenGL texture,
vertex buffer and GstVideoOverlayRectangle.
Transforms overlay coordinate space to vertex buffer space with aspect ratios in mind.

= Example Pipelines =

Simple pipeline

gst-launch-1.0 videotestsrc ! \
  textoverlay text="Hello World" font-desc="sans bold 30" ! \
  glimagesink

Display 3 static overlays at different positions

gst-launch-1.0 videotestsrc ! \
  textoverlay text="text1" valignment="top" font-desc="sans bold 30" ! \
  textoverlay text="text2" halignment="right" font-desc="sans bold 30" ! \
  textoverlay text="text3" halignment="left" font-desc="sans bold 30" ! \

of multiple view streams.

1e87053475 gl: new glbasebuffer GstMemory object 
Provides generic handling of GL buffer objects accessible using
the GL bind points (GL_ARRAY_BUFFER, GL_PIXEL_*_BUFFER).

Implementation based off the current GstGLMemory.

e80533dcee [793/906] add a GstGLContext object that will be the basis of OpenGL contexts 
At the moment it just sits in between GstGLDisplay and GstGLWindow
performing some of the stuff that GstGLWindow used to do.

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.
