THUMBNAIL_IS_VALID_NORMAL

A key in the "thumbnail" namespace for checking whether the normal thumbnail is outdated.

This attribute is true if the normal thumbnail is up-to-date with the file it represents, and false if the file has been modified since the thumbnail was generated.

If g_file_attribute_thumbnailing_failed_normal is true and this attribute is false, it indicates that thumbnailing may be attempted again and may succeed.

Corresponding FileAttributeType is g_file_attribute_type_boolean.
