/**
* How this effect works:
*
* Effect announces that it is around through property _KDE_KWIN_KSCREEN_SUPPORT on the root window.
*
* KScreen watches for this property and when it wants to adjust screens, KScreen goes
* through the following protocol:
* 1. KScreen sets the property value to 1
* 2. Effect starts to fade out all windows
* 3. When faded out the effect sets property value to 2
* 4. KScreen adjusts the screens
* 5. KScreen sets property value to 3
* 6. Effect starts to fade in all windows again
* 7. Effect sets back property value to 0
*
* The property has type 32 bits cardinal. To test it use:
* xprop -root -f _KDE_KWIN_KSCREEN_SUPPORT 32c -set _KDE_KWIN_KSCREEN_SUPPORT 1
*
* The states are:
* 0: normal
* 1: fading out
* 2: faded out
* 3: fading in
