-- A @PangoGlyphItemIter@ is an iterator over the clusters in a
-- @PangoGlyphItem@.
-- 
-- The *forward direction* of the iterator is the logical direction of text.
-- That is, with increasing /@startIndex@/ and /@startChar@/ values. If /@glyphItem@/
-- is right-to-left (that is, if @glyph_item->item->analysis.level@ is odd),
-- then /@startGlyph@/ decreases as the iterator moves forward.  Moreover,
-- in right-to-left cases, /@startGlyph@/ is greater than /@endGlyph@/.
-- 
-- An iterator should be initialized using either
-- 'GI.Pango.Structs.GlyphItemIter.glyphItemIterInitStart' or
-- 'GI.Pango.Structs.GlyphItemIter.glyphItemIterInitEnd', for forward and backward iteration
-- respectively, and walked over using any desired mixture of
-- 'GI.Pango.Structs.GlyphItemIter.glyphItemIterNextCluster' and
-- 'GI.Pango.Structs.GlyphItemIter.glyphItemIterPrevCluster'.
-- 
-- A common idiom for doing a forward iteration over the clusters is:
-- 
-- >PangoGlyphItemIter cluster_iter;
-- >gboolean have_cluster;
-- >
-- >for (have_cluster = pango_glyph_item_iter_init_start (&cluster_iter,
-- >                                                      glyph_item, text);
-- >     have_cluster;
-- >     have_cluster = pango_glyph_item_iter_next_cluster (&cluster_iter))
-- >{
-- >  ...
-- >}
-- 
-- 
-- Note that /@text@/ is the start of the text for layout, which is then
-- indexed by @glyph_item->item->offset@ to get to the text of /@glyphItem@/.
-- The /@startIndex@/ and /@endIndex@/ values can directly index into /@text@/. The
-- /@startGlyph@/, /@endGlyph@/, /@startChar@/, and /@endChar@/ values however are
-- zero-based for the /@glyphItem@/.  For each cluster, the item pointed at by
-- the start variables is included in the cluster while the one pointed at by
-- end variables is not.
-- 
-- None of the members of a @PangoGlyphItemIter@ should be modified manually.
--
