 * FIXME: The whole concept of handling unicode is badly broken.
 *	many hook-messages expect a pointer to a
 *	OPENFILENAMEA or W structure. With the current architecture
 *	we would have to convert the beast at every call to a hook.
 *	we have to find a better solution but it would likely cause
 *	a complete rewrite after which we should handle the
 *	OPENFILENAME structure without any converting (jsch).
 *
 * FIXME: any hook gets a OPENFILENAMEA structure
 *
 * FIXME: CDN_FILEOK is wrong implemented, other CDN_ messages likely too
 *
 * FIXME: old style hook messages are not implemented (except FILEOKSTRING)
 *
 * FIXME: algorithm for selecting the initial directory is too simple
 *
 * FIXME: add to recent docs
 *
 * FIXME: flags not implemented: OFN_CREATEPROMPT, OFN_DONTADDTORECENT,
 * OFN_ENABLEINCLUDENOTIFY, OFN_ENABLESIZING,
 * OFN_NODEREFERENCELINKS, OFN_NOREADONLYRETURN,
 * OFN_NOTESTFILECREATE, OFN_USEMONIKERS
