RecentFilter can be used to restrict the files being shown in a RecentChooser.
Files can be filtered based on their name (with add_pattern()), on their mime type (with add_mime_type()), on the application that has registered them (with add_application()), or by a custom filter function (with add_custom()).
Filtering by mime type 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 RecentFilter 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 RecentChooser, see RecentChooser::add_filter(), but it is also possible to manually use a filter on a file with filter().
