956c4d0bde gl/format: use our own GL format enum's instead of gstvideo's 
They can describe in more detail (such as component sizes) the requested format.

0dc003bf30 gl/docs: massive update 
- add Since: markers where necessary.
- document structs
- add documentation headers for each module (short_description,
  see_also, etc)
- reduce the number of warnings gtk-doc outputs
- fix spelling mistakes

06b4b52a20 glcontext: remove not thread-safe get/set_error() 
Use GError's instead if necessary.

989200820d glmemory: add the texture type to allocate to parameters 
Rather than assuming something.  e.g. zerocopy on iOS with GLES3 requires
the use of Luminance/Luminance Alpha formats and does not work with
Red/RG textures.

c9d9077a5f glbasememory: take a pointer as the wrapped gpu handle 
Allows passing arbitrary data to wrap the the specific memory implementation
which is required for some memory implementations.

7685b052b8 glmemorypbo: unmap pbo memory on pbo read error 
Otherwise we are returning failure with a dangling map!

Also only unset the NEED_DOWNLOAD flag in download_transfer() if the read actually
succeeds.

04ec728722 glbasememory: Free the actual memory object when requested 
Otherwise we are leaking ~400B on each GstMemory allocation.

Freeing in the base class matches the GObject semantics.

3423e108d4 glmemorypbo: don't double read pixels 
The optimistic download_transfer was not setting the required flag to not
perform glReadPixels on subsequent map (READ). resulting in glReadPixels
happening twice.

Removes extremely similar code from glmemorypbo.

4717b48a03 glmemorypbo: fix wrapping data on GL 2.1 
GL 2.1 only supports pbo upload.

The wrapped data pointer was only being set on the pbo memory and on the
glmemory so when a download was requested (in GL 2.1), glmemory was
allocating a new data pointer and thus not returning the wrapped data.

49291bc927 glmemorypbo: only create a pbo memory if the context actually supports it 
e.g. GL <= 2.0 does not support pbo usage and GL 2.1 only supports pbo upload.

6917b3b35a glmemory: small code reformat 
makes the alloc_params selections fit on a single line.

c4e5423f3b glmemorypbo: Comment out unused functions to fix compilation with clang 
It's not clear if these are intentionally unused or the code should be
changed, but this fixes compilation for the time being at least.

5dcd500257 gl*memory*: reverse the parameter order of user_data and destroy notify 
The convention is to have the destroy notify last after any user data

779dc3132c glmemorypbo: remove our own alloc()/wrapped()/etc functions

b12f2be4b1 glmemorypbo: map/unmap pbo memory correctly for state tracking 
Otherwise some downloads will fail to occur from the PBO.

2b7495bbc1 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.
