++ * Pre-calculated constants used for YCbCr narrow to full range scaling
++ * The base formula is the quantization formula derived from BT.2100 Table 9:
++ * Where Y' = Round [(219 * E′ + 16) * 2^(n−8)],
++ * Cb',Cr' = Round [(224 * E′ + 128) * 2^(n−8)]
++ * where E' is the signal value in [0,1] range and n is the bit depth. Round is rounding towards 0.
++ * For inputs, the inverse is used where we are solving for E' for a given Y'Cb'Cr' normalized by GPU
++ * in [0,1] range. The GPU will interpret color as a 16bit int value, and solving for E' becomes:
++ * E' = (Y' - 2^(n-4)) / (219 * 2^(n-8))
++ * E' = (Cb'Cr' - 2^(n-1)) / (7 * 2^(n-3))
++ * Y' and Cb'Cr' is in the range of [0, 2^n - 1] in original formula, we need to scale the value normalized to [0,1]:
++ * C = Y'Cb'Cr' * (2^n - 1)
++ * Which means the input scale = (2^n - 1) / (219 * 2^(n-8)) and input offset = 2^(n-4)) / (219 * 2^(n-8)) for Y' and
++ * 2^(n-1)) / (7 * 2^(n-3)) for Cb'Cr'
