Browse source 
It performs better when its less buggy

Compression changes for rgb_scanline_half_piz_dw_t08 (using float16 with remaping) from
56086 byte to 34371
(with a single slice its 28122 byte)

prior remap it was 188186 bytes

ACES_OT_VWG_SampleFrames/ACES_OT_VWG_SampleFrames improves too but only by a fraction of a percent
