MultiplyMatrixVector multiplies the matrix m with the point and returns the result.

(m *Matrix)

// MultiplyMatrixVector multiplies the matrix m with the point and returns the result.
func (p *Point) MultiplyMatrixVector(m *Matrix) *Point {
	x := m.Val[m00]*p.X + m.Val[m01]*p.Y + m.Val[m02]
	y := m.Val[m10]*p.X + m.Val[m11]*p.Y + m.Val[m12]
	p.X, p.Y = x, y
	return p
