A structure that has a starting point, a direction and a length that represents a line that has a starting point, and extends infinitely in one direction.


	VectorAligned  m_Start;	// starting point, centered within the extents
	VectorAligned  m_Delta;	// direction + length of the ray
	VectorAligned  m_StartOffset;	// Add this to m_Start to get the actual ray start
	VectorAligned  m_Extents;	// Describes an axis aligned box extruded along a ray
	bool	m_IsRay;	// are the extents zero?
	bool	m_IsSwept;	// is delta != 0?
