Public Member Functions
	FPS ()
void	show ()
	Prints the FPS.
void	frame (bool drawn)
	FPS counting function.
void	action ()
	Method that contains the thread's program code.
Public Member Functions inherited from Thread
	Thread ()
	Constructor Initializes the context using prepareContext with the highest aligned address of the reserved_stack_space array as stack pointer (top of stack). Furthermore, assign each thread a unique id using a global variable idCounter. You have to declare and initialize it properly.
void	go ()
	Activates the first thread on this CPU.
void	resume (Thread *next)
	Switches from the currently running thread to the next one.
Waitingroom *	getWaitingroom () const
	Returns the Waitingroom in which the thread is currently waiting.
void	setWaitingroom (Waitingroom *w)
	Marks the thread as waiting for an event in Waitingroom w.
