Sebastian Kügler ca172e2082 Force backgroundcontrast during slidingpopup animations
This fixes the sliding popups losing their contrast effect when
animating, less flicker.

In this patch, we temporarily force the contrast effect on, but only if
it hasn't been explicitely disabled. As soon as the animation stops, the
force flag is disabled again. For disappearing windows, we just set the
flag in the same way, but skip over the bookkeeping, since the window is
going to be deleted, anyway.
