/*
An outer box-shadow casts a shadow as if the border-box
of the element were opaque. Assuming a spread distance
of zero, its perimeter has the exact same size and
shape as the border box. The shadow is drawn outside
the border edge only: it is clipped inside the border-box
of the element.
If a spread distance is defined, the shadow perimeter
defined above is expanded outward (for outer box-shadows)
by outset withting the shadow’s straight edges by the spread
distance (and flooring the resulting width/height at zero).
