b5b7a3aec3 meson: add some starting build files for GL
Currently only works on linux with egl/glx + wayland/x11 but the general
principals have been layed out for adding the other GL platforms/winsys'.

c16d57cc9a glupload: create the GstGLUpload object in ::transform_caps
Previously it was created in the init function and destroyed in ::stop, which
lead to segfaults when reusing the element.

Now the upload object is created in ::transform_caps if it is NULL, which is the
earliest we need it. The other vfuncs already bail out if the upload object is
NULL, which means that negotiation wasn't done.

91fea30ff4 gstglupload: make the GLMemoryUpload method output the correct texture-target
Now when used with video/x-raw as input, the GLMemoryUpload method checks for
->tex_target in input GLMemory(es) and sets the output texture-target
accordingly.

Fixes video corruption with a pipeline like avfvideosrc ! video/x-raw !
glimagesink where on macos avfvideosrc pushes RECTANGLE textures but glupload
was configuring texture-target=2D as output.

3ca79c93ba glstereomix: Fix caps negotiation

back and broke glstereomix. Instead of doing nego incorrectly
in the find_best_format() vfunc, do it directly in the
update_caps() method.

061a157ef5 glvideomixer: fix race retrieving the GL context from the display
_get_gl_context() can be called concurrently from either propose_allocation() or
decide_allocation().  If it so happens that this happens at the same time,
the check for whether we already had a GL context was outside the lock.  Inside
the lock and loop, the first thing that happens is that we unref the current GL
context (if valid) as if there was a conflict adding it to the display.  If the
timing was unlucky, subsequent use of the GL context would be referencing an
already unreffed GL context object resulting in a critical:

g_object_ref: assertion 'object->ref_count > 0' failed

fe7dd131f5 gltestsrc: fix shaders ref counting
The gltestsrc element uses two shaders: color_shader and snow_shader.
Those are alternatively assigned to the SrcShader->shader pointer and
their reference was transferred to it. Only the SrcShader->shader was
unreffed (in _src_shader_deinit()) so only one shader was properly
freed, the other one was leaked.

Fixed this by giving an extra ref to SrcShader->shader and unreffing the
2 shaders in _src_smpte_free().

7507b14dcd gltransformation: use the affine transformation meta if available downstream
We can avoid a render pass if downstream supports the affine transformation meta
and increase the performance of some pipelines involving gltransformation.

Implemented by checking for the affine transformation in the allocation query
from downstream and combining our matrix with that of upstream's (or creating
our own).

ceec4ad873 glvideomixer: implement glBlendFunc and glBlendEquation
Allows more blending options than just A over B

e.g. frame comparisons are now possible.
  glvideomixer name=m
    sink_0::zorder=0
    sink_1::zorder=1
    sink_1::blend-equation-rgb={subtract,reverse-subtract}
    sink_1::blend-function-src-rgb=src-color
    sink_1::blend-function-dst-rgb=dst-color

8c02a47741 gleffects: fix shader compilation with legacy opengl
All the gleffects shaders can be run against a gles2 or a legacy opengl glsl
compiler but weren't being advertised as such.

Fixes gleffects under desktop opengl < 3.2.

15a28c8024 glshader: fix usage doc
The property location has been changed in favor of vertex/fragment
string properties; the doc had not been updated and was still referring
to the previous property; also, now the #version header has become mandatory

ebeae8bcdb glimagesink: Show error when video frame is not mapped.
Adds more meaningful error than
"Failed to convert multiview video buffer", which is always used
when prepare_next_buffer() fails in gst_glimage_sink_prepare().

6961945110 glmemory: add gst_gl_memory_allocator_get_default
Add gst_gl_memory_allocator_get_default to get the default allocator based on
the opengl version. Allows us to stop hardcoding the PBO allocator which isn't
supported on gles2.

Fixes GL upload on iOS9 among other things.

a3ebe19d87 glimagesink: don't deadlock on resize
Performing any GL function marshalling off the GL thread with glimagesink's
render lock is prone to deadlocks between the GL thread and the non-GL thread.

What can happen is this:
1. non-GL thread attempts to function marshal to the GL thread.
2. while 1 is happening, the winsys gives an event (say resize)
3. This calls back into glimagesink which taks the render lock.
4. As the GL function marshalling is attempting to run on the GL
   and already has glimagesink's render lock locked.  This deadlocks
   as the threads are waiting for each other.

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.
