/** A filter for selecting a file subset.
 *
 * A Gtk::FileFilter can be used to restrict the files being shown in a Gtk::FileChooser.
 * Files can be filtered based on their name (with add_pattern()), 
 * on their mime type (with add_mime_type()), or by a custom filter 
 * function (with add_custom()).
 *
 * Filtering by mime types handles aliasing and subclassing of mime types; 
 * e.g. a filter for text/plain also matches a file with mime type application/rtf, 
 * since application/rtf is a subclass of text/plain. Note that Gtk::FileFilter 
 * allows wildcards for the subtype of a mime type, so you can e.g. filter for image/ *.
 * 
 * Normally, filters are used by adding them to a Gtk::FileChooser. See Gtk::FileChooser::add_filter(). 
 * But it is also possible to manually use a filter on a file with filter().
