* FIXME: The whole concept of handling unicode is badly broken.
* many hook-messages expecting 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 if would likely cause
* a complete rewrite with after we shouldhandle 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: lpstrCustomFilter not handled
*
* FIXME: if the size of lpstrFile (nMaxFile) is too small the first
* two bytes of lpstrFile should contain the needed size
*
* 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_EXTENSIONDIFFERENT,
* OFN_NODEREFERENCELINKS, OFN_NOREADONLYRETURN,
* OFN_NOTESTFILECREATE, OFN_OVERWRITEPROMPT, OFN_USEMONIKERS
