// * Called as a function with a [VNF structure](vnf.scad) in the `p` argument, returns the translated VNF.
// * Called as a function with the `p` argument, returns the translated point or list of points.
// * Called as a function with the `p` argument set to a VNF or a polygon and `v` set to "centroid", "mean" or "box", translates the argument to the centroid, mean, or bounding box center respectively.
// * Called as a function without a `p` argument, with a 2D offset vector `v`, returns an affine2d translation matrix.
// * Called as a function without a `p` argument, with a 3D offset vector `v`, returns an affine3d translation matrix.
// * Called as a function without a `p` argument, returns a 4x4 translation matrix for operating on 3D data.

// Arguments:
// v = An [X,Y,Z] vector to translate by. For function form with `p` is a point list or VNF, can be "centroid", "mean" or "box".
// v = An [X,Y,Z] vector to translate by. For function form with `p` a point list or VNF, can be "centroid", "mean" or "box".
// p = Either a point, or a list of points to be translated when used as a function.
