The main purpose of the Gamma (GMA) function is to compensate for the non-linear characteristics of the sensor. GMA
converts the pixel values according to the Gamma curve to compensate the sensor output under different light strengths.
The non-linear gamma curve is approximately constructed with different linear functions. Raw gamma compensates the
image in the RAW domain.

Enable/Disable raw gamma mode.
