- * Problem:
- *     xml_tselem_start(), xml_tileset_end(), etc. may be called with one of two
- *     types of user data.
- * Possible solution:
- *  1. Create a base (struct xml_doc) in src/xml.h:
- *         struct xml_doc {
- *             enum {
- *                 XML_DOC_TMX,
- *                 XML_DOC_TSX
- *             } type;
- *             XML_Parser p;
- *         };
- *  2. Make (struct tmx) and (struct tmx) "extend" it, e.g.:
- *         struct tsx {
- *             struct xml_doc doc;
- *             struct tileset *ts;
- *         };
- *  3. Make xml_tselem_start(), xml_tileset_end(), etc. check the doc.type
- *     member of the user data and find the (struct tileset *) accordingly.
- * Wait, what?!
- * Alternative solution:
- *  1. Declare (struct tmx) in src/resources/map.h.
- *  2. Add to (struct tsx) the following member:
- *         struct tmx *parent_tmx;
- *  3. In xml_mapelem_start() (src/resources/map.c):
- *      1. Allocate a (struct tsx).
- *      2. Set the parent_tmx member of the (struct tsx) to tmx.
- *      3. Set the ts member of the (struct tsx) to ts.
- *      4. Set the (struct tsx) as the user data.
- *  4. In xml_tileset_end() (src/resources/tileset.c), add the following code:
- *         if (tsx->parent_tmx != NULL) {
- *             XML_SetUserData(tsx->p, tsx->parent_tmx);
- *             free(tsx);
- *             XML_SetStartElementHandler(tmx->p, xml_mapelem_start);
- *             XML_SetEndElementHandler(tmx->p, xml_map_end);
- *         }
- * Alternative alternative solution:
- *     Something that doesn't suck.
