-+ * Gamma ramp representation in DC
-+ *
-+ * A gamma ramp is just a curve defined within the range of [min, max] with
-+ * arbitrary precision.
-+ *
-+ * DM is responsible for providing DC with an interface to obtain any y value
-+ * within that range with a selected precision.
-+ *
-+ * bit32 ------------------------------------------------- bit 0
-+ * [ padding ][ exponent bits ][ fraction bits ]
-+ *
-+ * DC specifies the input x value and precision to the callback function
-+ * get_gamma_value as well as providing the context and DM returns the y
-+ * value.
-+ *
-+ * If fraction_bits + exponent_bits exceed width of 32 bits, get_gamma_value
-+ * returns 0. If x is outside the bounds of [min, max], get_gamma_value
-+ * returns 0.
