        <returns>The object of type <see cref="T:Pango.FontDescription" /> created.</returns>
        <remarks>The form of the string representation is "[FAMILY-LIST] [STYLE-OPTIONS] [SIZE]", where:
<list type="bullet"><item><term>FAMILY-LIST is a comma separated list of families optionally terminated by a comma.</term></item><item><term>STYLE-OPTIONS is a whitespace separated list of words where each WORD describes one of style, variant, weight, or stretch.</term></item><item><term>SIZE is a decimal number (size in points)</term></item></list><para>
Any one of the options may be absent. If FAMILY-LIST is absent, then the family_name field of the resulting font description will be initialized to NULL. If STYLE-OPTIONS is missing, then all style options will be set to the default values. If SIZE is missing, the size in the resulting font description will be set to 0.
