static size_t asx3d3_tin_size ( const LWTIN *  tin, char *  srs, int  precision, int  opts, const char *  defid  )

Need to make space for size of additional attributes, the coordIndex has a value for each edge for each triangle plus a space to separate so we need at least that much extra room

3 is to make space for coordIndex
