+/**
+ * ToneReproductionCurve - TRCs are used to describe RGB
+ * and Grayscale profiles. The TRC is essentially the gamma
+ * function of the color space.
+ *
+ * For example, Apple RGB has a gamma of 1.8, most monitors are ~2.2,
+ * sRGB is 2.4 with a small linear part near 0.
+ * Linear spaces are of course 1.0.
+ * (The exact function is implemented in SrgbConverter)
+ *
+ * The ICC specification allows the TRC to be described as a single
+ * Gamma value, where the function is thus out = in**gamma.
+ * Alternatively, the gamma function may be represented by a lookup table
+ * of values, in which case linear interpolation is used.
