//     Function: Builder::add_prim
//       Access: Public
//  Description: Adds the indicated nonindexed primitive, along with
//               its associated bucket, to the builder's internal
//               structures.  This copies all relevant information
//               into the builder.
//
//               Returns true if the primitive was successfully added,
//               false if it was invalid for some reason (for
//               instance, a polygon with two vertices).

//     Function: Builder::add_prim_nonindexed
//       Access: Public
//  Description: Adds the specified indexed primitive as if it were
//               nonindexed.  This simply looks up each coordinate
//               value on the prim in its associated array and stores
//               a nonindexed primitive with the actual coordinate
//               values, instead of the index numbers.
//
//               This is handy for having code that calls the builder
//               and might want to build either indexed or nonindexed
//               geometry, as selected by the user at run-time.
//               Simply build indexed geometry in all cases, then call
//               either add_prim or add_prim_nonindexed, according to
//               the user's selection.
