+Opacity is a PRODUCT of all opacities by default. E.g. `active_opacity` to 0.5 and
 windowrule opacity to 0.5 will result in a total opacity 0.25. You are allowed
 to set opacities over 1, but any opacity product over 1 will cause graphical
 glitches. E.g. `0.5 * 2 = 1`, and it will be fine, `0.5 * 4` will cause
