Valid Texture Gamma Values

• raw : Use texture data as it was read from the texture and do not mark it as using a specific color space.

• sRGB : Mark texture as sRGB when reading.

• auto : Check for gamma/color space metadata in the texture file itself; if metadata is indicative of sRGB, mark texture as sRGB. If no relevant metadata is found, mark texture as sRGB if it is either 8-bit and has 3 channels or if it is 8-bit and has 4 channels. Otherwise, do not mark texture as sRGB and use texture data as it was read from the texture.
