SweetFX parameters

[Be1n]

Have some confusion that need cleared up.

1. For SMAA, does increasing the values for

SMAA_MAX_SEARCH_STEPS 16
SMAA_MAX_SEARCH_STEPS_DIAG 6
SMAA_CORNER_ROUNDING 0

Improve the results?

2. What is the difference between the Bloom effect offered here, and the HDR/Bloom generated by the games?

3. Why are the RedC and GreenC under Cineon DPX set at 0.36, but the BlueC is set at 0.34?

4. Can't figure out what lumasharpen does.

Thanks.
