    // The defaultExtension, if non-empty, is
    // appended to the filename if the user fails to type an extension. The new
    // implementation (taken from FileSelectorEx) appends the extension
    // automatically, by looking at the filter specification. In fact this
    // should be better than the native Microsoft implementation because
    // Windows only allows *one* default extension, whereas here we do the
    // right thing depending on the filter the user has chosen.

    // suitable filter.
