GrayscaleEffect Constructor (IImageProvider, Double, Double, Double, Double)

Creates and initializes a new GrayscaleEffect with provided image source and specified weights. The gray shade is calculated by multiplying each color component of every pixel with the matching Weight and adding a constant: resultShade = redValue * redWeight + greenValue * greenWeight + blueValue * blueWeight + constant. The resulting shade is clamped to the range [0,1].
