5//! `PlayerGLContext` is a trait to be used to pass the GL context for
6//! rendering purposes.
7//!
8//! The current consumer of this trait is the GL rendering mechanism
9//! for the GStreamer backend.
10//!
11//! The client application should implement this trait and pass the
12//! trait object to its `player` instance.
