PangoGlyphVisAttr:
@is_cluster_start: set for the first logical glyph in each cluster. (Clusters
are stored in visual order, within the cluster, glyphs
are always ordered in logical order, since visual
order is meaningless; that is, in Arabic text, accent glyphs
follow the glyphs for the base character.)
The PangoGlyphVisAttr is used to communicate information between
the shaping phase and the rendering phase. More attributes may be
added in the future.
