The implementation class for a general Polygon as opposed to a specific Polygon such as a Square or a Rectangle, is encoded as a sequence of plain 2 dimension (mathematical) vectors. Minimum length 3. Clockwise is the default. Polygon may be altered to include a centre.

Index with foreach on the data elements. Performs a side effecting function on the index and each element of the data sequence. It takes a function as a parameter. The function may return Unit. If it does return a non Unit value it is discarded. The [U] type parameter is there just to avoid warnings about discarded values and can be ignored by method users. The method has 2 versions / name overloads. The default start for the index is 0 if just the function parameter is passed. The second version name overload takes an Int for the first parameter list, to set the start value of the index. Note the function signature follows the foreach based convention of putting the collection element 2nd or last as seen for example in fold methods' (accumulator, element) => B signature.

Returns the vertex of the given index. If the index is out of range, it will just circle round the vertices, so for a triangle -1 gives v2, -2 gives v1, 3 gives v0, 4 gives v1 etc. It will not throw unlike the unsafeVert method.

This method does nothing if the vertNum < 2. Foreach vertex applies the side effecting function to the previous vertex with each vertex. The previous vertex to the first vertex is the last vertex of the PolygonLike. Note the function signature (previous, vertex) => U follows the foreach based convention of putting the collection element 2nd or last as seen for example in fold methods'(accumulator, element) => B signature.
