linear [0, 1] -> gamma [0, 1] (not clamped).
Works for numbers outside this range (e.g. negative numbers).
linear [0, 1] -> gamma [0, 255] (clamped).
Values outside this range will be clamped to the range.
All ranges in 0-1, rgb is linear.
gamma [0, 255] -> linear [0, 1].
linear [0, 255] -> linear [0, 1].
Useful for alpha-channel.
