Description [src]
struct PangoLayoutLine {
PangoLayout* layout;

gint length;
GSList* runs;
guint is_paragraph_start : 1;
guint resolved_dir : 3;
}
A PangoLayoutLine represents one of the lines resulting from laying
out a paragraph via PangoLayout.
PangoLayoutLine structures are obtained by calling
pango_layout_get_line() and are only valid until the text,
attributes, or settings of the parent PangoLayout are modified.
