GstGLWindow represents a window that elements can render into. A window can either be a user visible window (onscreen) or hidden (offscreen).
typedef enum { GST_GL_WINDOW_ERROR_FAILED, GST_GL_WINDOW_ERROR_OLD_LIBS, GST_GL_WINDOW_ERROR_RESOURCE_UNAVAILABLE, } GstGLWindowError;
typedef struct _GstGLWindow GstGLWindow;
GstGLWindow is an opaque struct and should only be accessed through the provided api.
