<code>WrappedIndexBuffer</code> converts vertex indices from a non list based
mesh mode such as {@link Mode#TriangleStrip} or {@link Mode#LineLoop}
into a list based mode such as {@link Mode#Triangles} or {@link Mode#Lines}.
As it is often more convenient to read vertex data in list format
than in a non-list format, using this class is recommended to avoid
complicating classes used to process mesh data from an external source.
