The #PangoAttrList structure represents a list of attributes
that apply to a section of text. The attributes are, in general,
allowed to overlap in an arbitrary fashion, however, if the
attributes are manipulated only through pango_attr_list_change(),
the overlap between properties will meet stricter criteria.

Since the #PangoAttrList structure is stored as a linear list,
it is not suitable for storing attributes for large amounts
of text. In general, you should not use a single #PangoAttrList
for more than one paragraph of text.
