     * For Pix, Box, Pta and Numa, there are 3 standard methods for handling the
     * retrieval or insertion of a struct: (1) direct insertion (Don't do this
     * if there is another handle somewhere to this same struct!) (2) copy
     * (Always safe, sets up a refcount of 1 on the new object. Can be
     * undesirable if very large, such as an image or an array of images.) (3)
     * clone (Makes another handle to the same struct, and bumps the refcount up
     * by 1. Safe to do unless you're changing data through one of the handles
     * but don't want those changes to be seen by the other handle.) For Pixa
     * and Boxa, which are structs that hold an array of clonable structs, there
     * is an additional method: (4) copy-clone (Makes a new higher-level struct
     * with a refcount of 1, but clones all the structs in the array.) Unlike
     * the other structs, when retrieving a string from an Sarray, you are
     * allowed to get a handle without a copy or clone (i.e., that you don't
     * own!). You must not free or insert such a string! Specifically, for an
     * Sarray, the copyflag for retrieval is either: TRUE (or 1 or L_COPY) or
     * FALSE (or 0 or L_NOCOPY) For insertion, the copyflag is either: TRUE (or
     * 1 or L_COPY) or FALSE (or 0 or L_INSERT) Note that L_COPY is always 1,
     * and L_INSERT and L_NOCOPY are always 0.
