the dynamic background feature is enhanced and
becomes smarter. It understands snapped windows, windows
that touch the panel edge etc. The criteria in
order for the background to become solid are:
- any active window that is touching the panel
edge (that includes krunner)
- any inactive window that is snapped and touches
the panel edge (concerning its geometry: quarter-snapped or half-snapped)
- maximized windows
- an inactive window but keepAbove is touching
the panel edge (this catches also the yakuake case)
- panel popups
