--make head thickness margin and tail thickness
margin totally independent
--ability item: reanchor it based on the screen edge
like applets are already doing
--adjust tasks animations in order to take into
account the anchoring
--parabolic effect adjust calculations to use
new thickness margins
--each origin mouse area is now informin
the SunkEvents handler for the relevant
origin areas at the same time and this way
there is no events breakage when changing
from one sunked event origin area to another
--the sunked events origin and destination areas
are now released only when the event is NOT inside
any origin area or any destination. This way
no events breakage is appearing when changing from
destination area to origin area and vice versa.
--each applet has now its own Sunk events to handle,
and as such each applet can now have different paddings
and that does not create any issues or missing events
