GamutCompress v0.3

• Add Fuse version of GamutCompress tool. Works in Blackmagic Fusion Studio, DaVinci Resolve Studio, and DaVinci Resolve Lite. Thanks to Jacob Danell for the help!
• Add Matchbox version of GamutCompress tool for Filmlight's Baselight, Autodesk Flame and Assimilate Scratch thanks to @nick-shaw's contribution!
• Add Shadow Rolloff parameter. This reduces the effect of the gamut compression below the specified achromatic value. The idea is to reduce gamut compression of shadow grain. Shadow grain can have very large distances from achromatic, which can result in differences when inverting the transform. Altering shadow grain may also not be desirable in vfx workflows, especially in the inverse direction.
• Add helper function to the Nuke nodes which assists in calculating the maximum distance from achromatic.
  • The max distance ratios have a big effect on the resulting RGB ratios, which will become hue once the image is processed through a display rendering transform. Depending on the original camera gamut, and the distances of that camera gamut's primaries from the destination gamut's primaries, these hue ratios may be slightly different. Therefore it may be desirable to optimize the max distance values according to the source gamut.
  • Calculating the max distance values from a source image is also possible.
• Update default max distance values according to most common digital cinema source gamuts. See this post on acescentral for more information.
