fix parabolic effect and Tasks thickness

--this fixes the Tasks plasmoid thickness and
improves a small breakage in the parabolic effect.
The Tasks thickness is going to maximum when there
is a hoveredInded in plasmoid or in containment.
--the previous fix, fixes also a small breakage in
the parabolic effect animation. The breakage was
appearing when going from
applet->applet separator->task and directRender is
enabled
