TSL function for creating a chromatic aberration node for post processing.

@tsl
@function
@param {Node<vec4>} node - The node that represents the input of the effect.
@param {Node|number} [strength=1.0] - The strength of the chromatic aberration effect as a node or value.
@param {Node|Vector2} [center=null] - The center point of the effect as a node or value. If null, uses screen center (0.5, 0.5).
@param {Node|number} [scale=1.1] - The scale factor for stepped scaling from center as a node or value.
@returns {ChromaticAberrationNode}
