Classes
class	SkidMarkQuads

Public Member Functions
	SkidMarks (const AbstractKart &kart, float width=0.32f)
	Initialises empty skid marks.
	~SkidMarks ()
	Removes all skid marks from the scene graph and frees the state.
void	update (float dt, bool force_skid_marks=false, video::SColor *custom_color=NULL)
	Either adds to an existing skid mark quad, or (if the kart is skidding) starts a new skid mark quad.
void	reset ()
	Removes all skid marks, called when a race is restarted.

Private Attributes
const AbstractKart &	m_kart
	Reference to the kart to which these skidmarks belong.
bool	m_skid_marking
	True if the kart was skidding in the previous frame.
float	m_width
	Reduce effect of Z-fighting.
Material *	m_material
	Material to use for the skid marks.
std::shared_ptr< SP::SPShader >	m_shader
	Shader(alphablend) to use for the skid marks.
std::vector< std::unique_ptr< SkidMarkQuads > >	m_left
	Two skidmark objects for the left and right wheel.
std::vector< std::unique_ptr< SkidMarkQuads > >	m_right

Static Private Attributes
static const int	m_start_alpha = 200
	Initial alpha value.
static const int	m_start_grey = 32
	Initial grey value, same for the 3 channels.
static float	m_avoid_z_fighting = 0.005f
	Shared static so that consecutive skidmarks are at a slightly different height.
