this effect, derived from the Maximize one, will
take the place of the manual window position
animation that Plasma tooltip are using.
this should cause less problems as animationg
positions on X is very error prone, plus it's
less jarring when the tooltip sizes changes too,
since that gets animated as well (behavior similar
to Windows7 taskbar tooltips)
