-/*
- * This imagemap module started as a port of the original imagemap.c
- * written by Rob McCool (11/13/93 robm@ncsa.uiuc.edu).
- * This version includes the mapping algorithms found in version 1.3
- * of imagemap.c.
- *
- * Contributors to this code include:
- *
- * Kevin Hughes, kevinh@pulua.hcc.hawaii.edu
- *
- * Eric Haines, erich@eye.com
- * "macmartinized" polygon code copyright 1992 by Eric Haines, erich@eye.com
- *
- * Randy Terbush, randy@zyzzyva.com
- * port to Apache module format, "base_uri" and support for relative URLs
- *
- * James H. Cloos, Jr., cloos@jhcloos.com
- * Added point datatype, using code in NCSA's version 1.8 imagemap.c
- * program, as distributed with version 1.4.1 of their server.
- * The point code is originally added by Craig Milo Rogers, Rogers@ISI.Edu
- *
- * Nathan Kurz, nate@tripod.com
- * Rewrite/reorganization. New handling of default, base and relative URLs.
- * New Configuration directives:
- * ImapMenu {none, formatted, semiformatted, unformatted}
- * ImapDefault {error, nocontent, referer, menu, URL}
- * ImapBase {map, referer, URL}
- * Support for creating non-graphical menu added. (backwards compatible):
- * Old: directive URL [x,y ...]
- * New: directive URL "Menu text" [x,y ...]
- * or: directive URL x,y ... "Menu text"
- * Map format and menu concept courtesy Joshua Bell, jsbell@acs.ucalgary.ca.
- *
- * Mark Cox, mark@ukweb.com, Allow relative URLs even when no base specified
