The <feDropShadow> filter primitive creates a drop shadow of the input image. It is a shorthand filter, and is defined in terms of combinations of other filter primitives.
The result of the <feDropShadow> filter is equivalent to the following:
<feGaussianBlur in="alpha-channel-of-feDropShadow-in"
stdDeviation="stdDeviation-of-feDropShadow"/>
<feOffset dx="dx-of-feDropShadow" dy="dy-of-feDropShadow"
result="offsetblur"/>
<feFlood flood-color="flood-color-of-feDropShadow"
flood-opacity="flood-opacity-of-feDropShadow"/>
<feComposite in2="offsetblur" operator="in"/>
<feMerge>
<feMergeNode/>
<feMergeNode in="in-of-feDropShadow"/>
</feMerge>
