-/** Abstraction for an OpenGL rendering context. In order to perform
- OpenGL rendering, a context must be "made current" on the current
- thread. OpenGL rendering semantics specify that only one context
- may be current on the current thread at any given time, and also
- that a given context may be current on only one thread at any
- given time. Because components can be added to and removed from
- the component hierarchy at any time, it is possible that the
- underlying OpenGL context may need to be destroyed and recreated
- multiple times over the lifetime of a given component. This
- process is handled by the implementation, and the GLContext
- abstraction provides a stable object which clients can use to
- refer to a given context. */
