--provide a minimum window thickness for docks at 384px.
and afterwards use maxiconsize, maxmargin etc calculations
in order to use greater window thicknesses
--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
--plasma themes because of their svg nature can
have a minimum padding under which they are not
drawn correctly. In such cases background shadows
overlap and background internal drawing overlaps
in the center. That property protects from
such case by introducing a minimum background
thickness at all cases. Good example of the issue
is observed in behaveAsPlasmaPanel(s) that are
floating and have very good round corners.
