Color grading modes.
public enum GradingMode
This mode allows you to provide a custom 3D LUT authored in an external software.
This mode is aimed at platforms that support HDR rendering. All the color operations will be applied in HDR and stored into a 3D log-encoded LUT to ensure a sufficient range coverage and precision (Alexa LogC El1000).
This mode is aimed at lower-end platforms but it can be used on any platform. Grading is applied to the final rendered frame clamped in a [0,1] range and stored in a standard LUT.
