* Fixed log2 shaper equations. Added bspline sampling for lut. Added options for custom log2 or linear lut with custom exposure ranges. Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Added support for PQ shaper. Added shader option & cvar for lut sampling quality. Fixed issues in the blend lut shader that were causing considerable quality loss. No longer always changing to the log2 1000 nit shaper when blending luts - if the source luts all use the same shaper, keep using that shaper in the blended lut. Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Fixed an integer -> float Signed-off-by: Ken Pruiksma <pruiksma@amazon.com> * Minor PR reveiw updates Signed-off-by: Ken Pruiksma <pruiksma@amazon.com>
