WebGLContextBusyMap

A map which tracks whether a given WebGL context is “busy” ie whether WebRender has currently taken a surface from its [SwapChain] for rendering purposes. Contexts will only be deleted once no WebRender instance is using it for rendering. This ensures that all Surfman Surfaces can be released properly on the WebGLThread.
