getLinesReadonly
Returns the lines of the @layout as a list.
This is a faster alternative to method@Pango.Layout.get_lines, but the user is not expected to modify the contents of the lines (glyphs, glyph widths, etc.).
Return
a GSList containing the lines in the layout. This points to internal data of the PangoLayout and must be used with care. It will become invalid on any change to the layout's text or properties. No changes should be made to the lines.
