gl-get-list returns four values: the red, green, blue, and alpha values used to clear the accumulation buffer. Integer values, if requested, are linearly mapped from the internal floating-point representation such that 1.0 returns the most positive repre‐ sentable integer value, and -1.0 returns the most negative representable integer value. The initial value is (0, 0, 0, 0). See glClearAccum.
