+       Get extensions of additional audio procs. These extensions may be specified by
+       newly installed IO procs in MMPM2.INI or by using the Multimedia setup. For
+       example the MMIOMP3 procedure for reading MP3 files adds the MP3 extension this
+       way to the system. Extensions already handled by a specialized class will be
+       filtered in the called REXX script e.g. MP3 so only unknown extensions end up here.
+
+       Strangely enough wpclsQueryInstanceFilter() is called during wpclsInitData() so
+       we query the extensions here before calling the parent.
+
+       FIXME:
+       The check is only done once during initialization. This is a little annoyance for
+       the user because new extension specified in the settings will only be picked up
+       on next WPS start.
