Parameters:

output	Output readout; altered and returned
inputs	Array of input readouts (F32 image and weight, U8 mask)
zero	Zero corrections to subtract from input, or NULL
scale	Scale corrections to divide into input, or NULL
params	Combination parameters

		psF32	rejThreshold,
		psF32	gradLimit
	)

Parameters:

images	Array of input images
masks	Array of input image masks
errors	The pixels which were rejected in the combination
inToOut	Transformation from input to output system
outToIn	Transformation from output to input system
rejThreshold	Rejection threshold
gradLimit	Gradient limit
