Public Member Functions
	Point ()
	Construct a 3D point at (0,0,0) with contrast 0 and color values (r,g,b,a) = (0,0,0,255)

void	setNaN ()
	Invalidate the point (set it to Not-a-Number)

bool	isNaN () const
	Check whether the point is valid (Not-a-Number)

void	setRgba (unsigned char r, unsigned char g, unsigned char b, unsigned char a)
	Set the r,g,b and alpha color value for the point.

void	setRgb (unsigned char r, unsigned char g, unsigned char b)
	Set the r,g,b color value for the point.

void	setIntensity (unsigned char val)
	Set the intensity for the point (sets r,g and b to identical values)

void	setContrast (float value)
	Set the contrast for the point.

unsigned char	alpha ()
	Get the alpha value for the point.

unsigned char	red () const
	Get the red color value for the point.

unsigned char	green () const
	Get the green color value for the point.

unsigned char	blue () const
	Get the blue color value for the point.

unsigned char	intensity ()
	Get the intensity of the point.
