code: def merge(self, other):
          
          cairo.cairo_font_options_merge(self._pointer, other._pointer)
          _check_status(cairo.cairo_font_options_status(self._pointer))
docs: Merges non-default options from :obj:`other`,
          replacing existing values.
          This operation can be thought of as somewhat similar
          to compositing other onto options
          with the operation of :obj:`OVER <OPERATOR_OVER>`.
