public class LayoutLine
A `PangoLayoutLine` represents one of the lines resulting from laying out a paragraph via `PangoLayout`.
`PangoLayoutLine` structures are obtained by calling [method@Pango.Layout.get_line] and are only valid until the text, attributes, or settings
of the parent `PangoLayout` are modified.
