Classes
class	Node
Public Member Functions
	ColorStack ()
	Default constructor.
	~ColorStack ()
	Destructor.
void	initialize ()
	init (takes current GL context/ like glInitNames (); glPushName (0))
bool	initialized () const
	has it been initialized?
bool	setMaximumIndex (unsigned int _idx)
	sets the maximum index number used in current node
void	setIndex (unsigned int _idx)
	sets the current color the given index (like glLoadName)
Vec4uc	getIndexColor (unsigned int _idx)
	gets the color instead of setting it directly
void	pushIndex (unsigned int _idx)
	creates a new node the stack (like glPushName)
void	popIndex ()
	pops the current node from the stack (like glPopName)
std::vector< unsigned int >	colorToStack (Vec4uc _rgba) const
	converts the given color to index values on the stack
unsigned int	freeIndicies () const
	returns maximal available index count
bool	error () const
	Did an error occur during picking.
unsigned int	currentIndex () const
	returns the current color index
