class Player()

The Player object handles initializing the player, holds state, and handles events for updating state.

Player.deferredResize

Store the size and position of the window before entering fullscreen and use this to correctly position the window when exiting fullscreen

Player.id

Player.isFullscreen

GET isFullscreen returns true if the video is running in fullscreen mode
