24 * A specialization on EggBinMaker for making polysets that share the same
25 * basic rendering characteristic. This really just defines the example
26 * functions described in the leading comment to EggBinMaker.
27 *
28 * It makes some common assumptions about how polysets should be grouped; if
29 * these are not sufficient, you can always rederive your own further
30 * specialization of this class.
