represents a connection to the underlying windowing system. +Elements are required to make use of #GstContext to share and propagate +a #GstGLDisplay. + +There are a number of environment variables

Common values are + 'x11', 'wayland', 'win32' or 'cocoa'. +- GST_GL_PLATFORM influences the OpenGL platform to use. Common values are + 'egl', 'glx', 'wgl' or 'cgl'. +- GST_GL_API influences the OpenGL API requested by the OpenGL platform. + Common values are 'opengl', 'opengl3' and 'gles2'. + +> Certain window systems require a special function to be called to +> initialize threading support.
