The CoglOutput object represents one output such as a monitor or laptop panel, with information about attributes of the output such as the position of the output within the global coordinate space, and the refresh rate. We don't yet publically export the ability to get output information but we track it for the GLX backend, where we'll use it to track the refresh rate.
