[effects/slideback] Consider windows which do have painting disabled as not usable

Authored by graesslin on Apr 15 2017, 10:02 AM.



On Wayland it can happen that a window is still in the stacking order
although it is not visible. This is mostly the case for Plasma windows.
So far the slideback effect did not ignore those windows and as they are
higher in the stacking order than most other windows it blocked the
effect from working once a Plasma panel element got closed.

This change considers a window which has painting disabled in the
stacking order as not usable and thus filters out all those windows.
