1dfeae2c42 gl: split glcolorconvert usage from glupload
the separation allows the transfer operation to occur in a separate
thread/time which may increase performance in specific circumstances.

6491af9ffc glupload: provide the output buffer that is rendered into
Allows callers to properly reference count the buffers used for
rendering.

Fixes a redraw race in glimagesink where the previous buffer
(the one used for redraw operations) is freed as soon as the next
buffer is uploaded.

1. glimagesink uploads in _prepare() to texture n
1.1 glupload holds buffer n
2. glimagesink _render()s texture n
3. glimagesink uploads texture n+1
3.1 glupload free previous buffer which deletes texture n
3.2 glupload holds buffer n+1
4. glwindow resize/expose
5. glimagesink redraws with texture n

The race is that the buffer n (the one used for redrawing) is freed as soon as
the buffer n+1 arrives.  There could be any amount of time and number of
redraws between this event and when buffer n+1 is actually rendered and thus
replaces buffer n as the redraw source.

30c6efc432 gl/mem: allocate the memory per plane
This patch provides the basic infrastructure required for this.
Upload and Download has been ported to this.

Has the nice effect of allowing GstGLMemory to be our
refcounted texture object for any texture type (not just RGBA).

Should not lose any features/video formats.

5168d86d9e [867/906] glupload: Add GRAY8/GRAY16LE/BE upload support to glimagesink
the 16bit data is uploaded as LUMINANCE_ALPHA, then expanded, composed
in shader. value weight is a little complicate, high byte weight is
255*256/65535 (denormalize to [0~255] ,shift to high byte,then normalize
to [0~1]), low byte weight is 255/65535(similar)

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.
