CGDisplayErr CGSetDisplayTransferByTable (
   CGDirectDisplayID display,
   CGTableCount tableSize,
   const CGGammaValue * redTable,
   const CGGammaValue * greenTable,
   const CGGammaValue * blueTable
);

OK, maybe I was being confused by the use of the term "Gamma". I read this as
being a way of setting a gamma curve by by setting the gamma value
(ie. one value per color, e.g. 1.8 or 2.2), rather than a table of values
defining a transfer curve. Thanks for clearing that up.
