Uses the pixel values from a second input to spatially displace the first input image.

DOM object: SVGFEDisplacementMapElement
SVG2 spec: https://www.w3.org/TR/filter-effects/#feDisplacementMapElement

This element is defined within a "<filter>" element, and is combined with other filter primitives to define a filter applied on the input image.

Example usage:

<filter id="MyFilter">
  <feTurbulence type="turbulence" baseFrequency="0.05" result="noise" />
  <feDisplacementMap in="SourceGraphic" in2="noise" scale="20" />
</filter>

Attribute	Default	Description
scale	0	Maximum displacement in user units.
xChannelSelector	A	Channel (R, G, B, A) of in2 used for x displacement.
yChannelSelector	A	Channel (R, G, B, A) of in2 used for y displacement.

Inherits standard filter primitive attributes (in, in2, result, x, y, width, height) from donner::svg::SVGFilterPrimitiveStandardAttributes.
