Owen W. Taylor 88d8bd84f2 Add CoglOutput and track for the GLX backend
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.
