NonpersistentSwitch
This node is identical to the Switch node, except that the in control is reset to 0 whenever the file is loaded (the value
you set it to in your current session is never saved to the .katana file).
This is useful for switches you may want to use interactively (low-quality settings, etc), that you don't want to
mistakenly have set for a batch render. Using a NonpersistentSwitch ensures that batch renders always get the left-
most input to the node.
OCIOCDLTransform
This node applies an ASC CDL grade. The calculation uses output = (i * s + o)^p where i is the input value, s is slope,
o is offset and p is power.
