“xrandr --gamma” sets inverted values and therefore disagrees with output of “xrandr --verbose”

Description
Setting “xrandr --output … --gamma i:j:k” for some i, j, k > 0 results in a gamma correction with the values 1/i, 1/j, and 1/k. These inverse values are then also (correctly) reported by “xrandr --verbose”.
This bug is probably related to bug 31517.
Expected Behaviour
“xrandr --gamma” should set the gamma values as given on the command line. Then these values also agree with the output of “xrandr --verbose”.
