\brief Custom predefined Noise fill filter.
Basic noise fill and transparency texture
Filter's parameters:
* Turbulence type (enum, default fractalNoise else turbulence) -> turbulence (type)
* Horizontal frequency (*1000) (0.01->10000., default 20) -> turbulence (baseFrequency [/1000])
* Vertical frequency (*1000) (0.01->10000., default 40) -> turbulence (baseFrequency [/1000])
* Complexity (1->5, default 5) -> turbulence (numOctaves)
* Variation (1->360, default 1) -> turbulence (seed)
* Dilatation (1.->50., default 3) -> color (n-1th value)
* Erosion (0.->50., default 1) -> color (nth value 0->-50)
* Color (guint, default 148,115,39,255) -> flood (flood-color, flood-opacity)
* Inverted (boolean, default false) -> composite1 (operator, true="in", false="out")
