Public Member Functions
	ColorStack ()
	Default constructor.

	~ColorStack ()
	Destructor.

void	initialize (ACG::GLState *)
	init (takes current GL context/ like glInitNames (); glPushName (0))

bool	initialized () const
	has it been initialized?

bool	setMaximumIndex (size_t _idx)
	sets the maximum index number used in current node

void	setIndex (size_t _idx)
	sets the current color the given index (like glLoadName)

Vec4uc	getIndexColor (size_t _idx)
	gets the color instead of setting it directly

void	pushIndex (size_t _idx)
	creates a new node the stack (like glPushName)

void	popIndex ()
	pops the current node from the stack (like glPopName)

std::vector< size_t >	colorToStack (Vec4uc _rgba) const
	converts the given color to index values on the stack

size_t	freeIndicies () const
	returns maximal available index count

bool	error () const
	Did an error occur during picking.

size_t	currentIndex () const
	returns the current color index
