ray: add rudimentary gamma correction
color banding has been quite visible, and somewhat expected with a
direct conversion from the linear float color space to the 8-bit
integral rgb color components.
A simple lookup table is used here to non-linearly map the values, table
generation is taken from Greg Ward's REAL PIXELS gem in Graphics Gems II.
