Constructor & Destructor Documentation

RU_LevelsFunc::RU_LevelsFunc	(	float	effect,
		float	global_in_range_min,
		float	global_in_range_max,
		float	global_out_range_min,
		float	global_out_range_max,
		float	global_gamma,
		float	comp_in_range_min[4],
		float	comp_in_range_max[4],
		float	comp_out_range_min[4],
		float	comp_out_range_max[4],
		float	comp_gamma[4]
	)

passing all data down, rather than precomputing MAdds, so that we can correctly handle the degenerate cases of 0-width input ranges.

Parameters

effect frame scope effect, applied by the ctor to the ranges but not the gammas (caller should apply it to the gammas)
