Description Martin Flöser 2013-05-18 18:59:48 UTC

Let's improve the screen switching experience for the case that screens are changed with KScreen:

1. KScreen informs KWin that it wants to change the screen setup
2. KWin fades the screen to black (to prevent flicker)
3. KWin informs KScreen once the screen is black
4. KScreen changes screen setup
5. KScreen informs KWin that new setup is configured
6. KWin adjusts the internal state (displayWidth/Height) and fades windows in again

Helper effect for KScreen integration

This effect is controlled by KScreen. It fades out all windows when
KScreen requests this and gives feedback to KScreen once all windows are
faded out. This allows KScreen to adjust the screens in a flicker free
way.
