-- <description>
-- Gtk_Paper_Size handles paper sizes. It uses the standard called
-- "PWG 5101.1-2002 PWG: Standard for Media Standardized Names" to name the
-- paper sizes (and to get the data for the page sizes). In addition to
-- standard paper sizes, Gtk_Paper_Size allows to construct custom paper
-- sizes with arbitrary dimensions.
--
-- The Gtk_Paper_Size object stores not only the dimensions (width and height)
-- of a paper size and its name, it also provides default print margins.
