*
* #GstGLUpload is an object that uploads data from system memory into GL textures.
*
* A #GstGLUpload can be created with gst_gl_upload_new() or found with
* gst_gl_display_find_upload().
*
* All of the _thread() variants should only be called within the GL thread
* they don't try to take a lock on the associated #GstGLDisplay and
* don't dispatch to the GL thread. Rather they run the required code in the
* calling thread.
* A #GstGLUpload can be created with gst_gl_upload_new()
