Darken the background when entering the window switcher (155 value for
opacity seems to give a good contrast between the background and the
current choosen window)
The background opacity animation is set to match the one from the dock actor
(250ms animation duration as well as the animation mode EASE_OUT_CUBIC)
When switching to the next window, other windows now don't disappear, but
instead, they are changing their z_position to -100 (a more subtle effect
from the previous -200 Z value) and faded with BrightnessContrastEffect
supplied with the brightness matching the brightness of the background
(-BACKGROUND_OPACITY / 255.0f).
