8930bf7c07 gl: unref display/other-context in the correct place
Otherwise state changes from PLAYING->READY->PAUSED will cause there to
to be no display configured on the element.

52a40dfc48 glmixer: Possible null pointer dereference
While printing error message when context fails, error variable is not being used anymore
so it will lead to null pointer dereference

66a5cad6c1 gldisplay: synchronize the searching and creation of GstGLContext's
Ootherwise we could end up with multiple elements in different chains
each creating a context.  Fixes context creation with glvideomixer.

9827138061 glmixer: fix caps leak in gst_gl_mixer_pad_sink_getcaps()
Caps refcounting was all wrong in this function. Rewrote it and add some
comments to make it clearer.

Fix caps leaks with the
validate.file.glvideomixer.simple.play_15s.synchronized scenario.

293d6a7ebe glmixer: pass the proper free function to frames and buffers array
'array_buffers' contain borrowed GstBuffer and so shouldn't have a free
function. 'frames' is the one containing GstGLMixerFrameData and so should use
_free_glmixer_frame_data as free function.

Fix GstGLMixerFrameData leaks with the
validate.file.glvideomixer.simple.play_15s.synchronized scenario.

4860e179fa gl: initial support for texture targets other than GL_TEXTURE_2D
Make GstGLMemory hold the texture target (tex_target) the texture it represents
(tex_id) is bound to. Modify gst_gl_memory_wrapped_texture and
gst_gl_download_perform_with_data to take the texture target as an argument.

This change is needed to support wrapping textures created outside libgstgl,
which might be bound to a target other than GL_TEXTURE_2D. For example on OSX
textures coming from VideoToolbox have target GL_TEXTURE_RECTANGLE.

With this change we still keep (and sometimes imply) GL_TEXTURE_2D as the
target of textures created with libgstgl.

API: modify GstGLMemory
API: modify gst_gl_memory_wrapped_texture
API: gst_gl_download_perform_with_data

8f86923b00 gl: add a sync meta for synchronizing across GL contexts
A context can create a GLsync object that can be waited on in order
to ensure that GL resources created in one context are able to be
used in another shared context without any chance of reading invalid
data.

This meta would be placed on buffers that are known to cross from
one context to another.  The receiving element would then wait
on the sync object to ensure that the data to be used is complete.
