 * gemtk_obj_tree_copy
 *
 * Copy a complete object-tree including all substructures (optional).
 *
 * CAUTION: The object-tree *must* have the LASTOB-flag (0x20) set in
 * it's physically last member.
 *
 * BUG: Up to now tree_copy won't copy the color-icon-structure,
 * because I'm too lazy ;) Maybe I'll do that one day. If you need it
 * urgently, contact me and force me to work... Btw, this doesn't mean
 * that G_CICONs won't be copied at all, but the copied tree will
 * share the CICONBLKs with the original.
 *
 * Input:
 * tree: Pointer to tree which should be copied
 * what: Specifies what substructures should be copied, too (see the
 *       C_xxx-definitions in tree-copy.h for details)
 *
 * Output:
 * NULL: Tree couldn't be copied (due to lack of memory)
 * otherwise: Pointer to copied tree, use free to dealloc it's memory
