Functions
static Output *	get_output_by_id (xcb_randr_output_t id)
Output *	get_output_by_name (const char *name)
	Returns the output with the given name if it is active (!) or NULL.
Output *	get_first_output ()
	Returns the first output which is active.
Output *	get_output_containing (int x, int y)
	Returns the active (!) output which contains the coordinates x, y or NULL if there is no output which contains these coordinates.
Output *	get_output_most (direction_t direction, Output *current)
	Gets the output which is the last one in the given direction, for example the output on the most bottom when direction == D_DOWN, the output most right when direction == D_RIGHT and so on.
void	initialize_output (xcb_connection_t conn, Output output, Workspace *workspace)
	Initializes the specified output, assigning the specified workspace to it.
