Work in progress on multi-display support:
* Added display parameter to many internal functions so video modes can be set on displays that aren't the public current one.
* The fullscreen mode is associated with fullscreen windows - not displays, so different windows more naturally have a mode associated with them based on their width and height. It's no longer necessary to specify a fullscreen mode, a default one will be picked automatically for fullscreen windows.
