 RGB = dac2rgb(DAC, GammaTable)

 DAC contains the frame buffer values of the 3 color planes, in the form
    of [DAC_r DAC_g DAC_b], where DAC_x can be a matrix. DAC values should
    be in the range [0 1].
 RGB is the linear intensity of each gun, returned in the form of [r g b].
    To separate the r,g,b planes, use GetPlanes.

 GammaTable -- the look up table to go from DAC to linear RGB
    If it has one column, all DAC values are changed according to this
    If it has 3 columns and more than one row, treat input image as
       3 planes and transform to RGB with the corresponding column.
    If it is a scalar number, raise the DAC values to this power.
    If it is a 3 vector, raise the r,g,b DAC values to the respective
       power.
    If GammaTable is not given, use a default scalar of 2.2.
    The entries in GammaTable are assumed to be in the range [0, 1].
