Setting gamm requires 6 fields instead of 2 #8
Description
The wrapper requires setting gamm to be an array of 6 numbers, whereas the example and type state the array should have 2 elements. The confusion arises because LibRaw uses a 6-element array internally, but expects only the first two fields to be set by the user. The JS API should thus require a 2-element array and leave the remaining 4 values of params.gamm unset. Currently, passing a 2-element array has no effect.
LibRaw documentation:
Sets user gamma-curve. Library user should set first two fields of gamm array:
Remaining 4 values are filled automatically.
