--playing around with Kirigami.ShadowedRectangle in order
to provide a nice beautiful custom made panel background
that the user can chosen custom radius or shadow size.
Colors are going to be used totally based on current plasma
theme.
--Plasma::FrameSvgItem margins are not consintent
in order to provide helpful hints how plasma theme
panel-background svg is drawn properly. The new
approach calculates paddings based on top,left,bottom,right
svg elements and in that way a consistent a properly
background.minimumThickness is discovered.
--was changed to 60Hz from 20Hz and also
the first call is immediately draw and then
the timer in triggered in order to block all
other calls. Hopefully this will be enough
for smooth moving blurring areas.
BUG:422209
--implementation is much more concrete now and we
need to be 1px precise in order to provide good
snapping and dodge visibility modes correctly
--in upcoming commit the view is touched property
will mean without window is touching the view edge.
For view edges touching there will be a different
variable that can be used from containment and
applets.
--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.
--Blur area is not updated instantly any more
and does not make too many unnecesary calls.
A timer was added to orchestrate this in order
for the Effects area to be updated at maximum
20times/sec.
--Dont animate the view container at all cases, that
creates a much smoother experience for the user in
editing mode
