dont block tooltips for zoom scale=1

--trying to combine dock mode, panel mode and
parabolic effect with plasma applets current implementation

criteria to activate the Latte MouseArea. The
user can still lock plasmoids that want the
Hover Default Plasmoid behavior or use the
Latte protocol to understand when they are in a Latte
containment.
