Gdk::Atom is an opaque type representing a string as an index into a table of strings on the X server
Each window under X can have any number of associated properties attached to it. Properties are arbitrary chunks of data identified by atoms. (An atom is a numeric index into a string table on the X server. They are used to transfer strings efficiently between clients without having to transfer the entire string.) A property has an associated type, which is also identified using an atom.
