- Remove SHALF constant so that we get back the original value when
calling UpScale then downscale with rounding
- Make the linear->gamma precomputed table bigger (8 bits rather than 5)
- Round values in kLinearToGammaTabS

Remove unused constants.
Use ALL_CAPS for defines and kCamelCase for static const values.
Change some defines into static constants if they are not used in array sizes.
