	Bow ()
TableSet &	law ()
	The law, for its own parameters (a table, a rosin).
const TableSet &	law () const
void	set_velocity_su (float su)
	How fast the bow travels across the string. Smoothed.
void	set_pressure_su (float su)
	How hard it presses: which force slice the law reads. Zero is no contact. Smoothed.
void	advance (uint16_t n)
	A block's worth of port movement.
float	excite (const JunctionState &j)
	One sample: the force on the string for the junction's state.
float	energy () const
	A bow stores nothing: it only does work on the string.
void	reset ()
bool	sticking () const
	True while the bow holds the string (with weight on it).
float	limit () const
	The static limit the bow holds the string with right now, in wave units.
float	force () const
	The force injected on the last sample, in wave units.
diagram::Ports	describe (diagram::Graph &g, uint8_t group, const char *name="bow") const
	The velocity source into the friction junction. Never called from audio code.
