New API: - gst_gl_context_get_config() - gst_gl_context_request_config() A GL context configuration is a GstStructure that has some well-known names for common values that can also be extended in platform-specific ways if necessary. Wrapped OpenGL contexts may be able to retrieve the GL context configuration depending on the platform. If that information is available, GstGLContext will attempt to create an context that matches the shared OpenGL context config unless gst_gl_context_request_config() has been called. A new environment variable 'GST_GL_CONFIG' will be read to influence the configuration chosen. The environment variable will only be used as a fallback if gst_gl_context_request_config() has not been called.
