-/** \class SkPerlinNoiseShader
-
-    SkPerlinNoiseShader creates an image using the Perlin turbulence function.
-
-    It can produce tileable noise if asked to stitch tiles and provided a tile size.
-    In order to fill a large area with repeating noise, set the stitchTiles flag to
-    true, and render exactly a single tile of noise. Without this flag, the result
-    will contain visible seams between tiles.
-
-    The algorithm used is described here :
-    http://www.w3.org/TR/SVG/filters.html#feTurbulenceElement

-     *  generated in the [1, -1] range, the output is brought back in the [0, 1] range by doing :
-     *  kFractalNoise_Type : noise * 0.5 + 0.5
-     *  kTurbulence_Type   : abs(noise)
-     *  Very little differences between the 2 types, although you can tell the difference visually.
