sdShow node
The sdShow and sdShow 2 node convert a signed distance image into a grayscale image whose background is black and the shape described by its input is white.
The sdShow 2 node fixes the distance when it is distorted, and consequently generates shapes with more consistent bevel width.

Inputs
The sdShow node accepts an input in signed distance function format.
Outputs
The sdShow node generates a grayscale output.
Parameters
The sdShow node accepts the width of the gradient (from white to black) around the input shape as well as the base value of the output as parameters.
