The DisplacementFilter class uses the pixel values from the specified texture (called the displacement map) to perform a displacement of an object. You can use this filter to apply all manor of crazy warping effects Currently the r property of the texture is used offset the x and the g property of the texture is used to offset the y.
The texture used for the displacement map * must be power of 2 texture at the moment
Sets the map dimensions uniforms when the texture becomes available.
Syncs the uniforms between the class object and the shaders.
The texture used for the displacement map. Must be power of 2 texture.
The offset used to move the displacement map.
Array an array of filter objects
An array of passes - some filters contain a few steps this array simply stores the steps in a liniear fashion. For example the blur filter has two passes blurX and blurY.
The multiplier used to scale the displacement result from the map calculation.
