Instance properties

int	A	The A component of this vector, which extends outward from the origin at a 54° angle counter-clockwise (SVG) or clockwise (geometry) from the x-axis.
int	B	The B component of this vector, which extends outward from the origin at an 18° angle counter-clockwise (SVG) or clockwise (geometry) from the x-axis.
int	C	The C component of this vector, which extends outward from the origin at an 18° angle clockwise (SVG) or counter-clockwise (geometry) from the x-axis.
int	D	The D component of this vector, which extends outward from the origin at a 54° angle clockwise (SVG) or counter-clockwise (geometry) from the x-axis.
Pentavector	DivideByPhi	Returns a new Pentavector whose direction is the same as this vector, but with a length multiplied by 1/φ. φ is the golden ratio ((√(5)+1)/2).
Pentavector	MultiplyByPhi	Returns a new Pentavector whose direction is the same as this vector, but with a length multiplied by φ. φ is the golden ratio ((√(5)+1)/2).
