Where is pango_glyph_item_free()?

[Jeff Franks <jcf tpg com au>]

Hi,

I am writing a C++ wraper for PangoGlyphItem and have noticed that 
pango_glyph_item_free() is missing. It is documentated in 
pango-Glyph-Storage.html and from examining the source code for 
functions like pango_glyph_item_split() and 
pango_glyph_item_apply_attrs() and pango_layout_iter_get_run(), not only 
the PangoGlyphItem returned needs to be freed but the PangoItem and 
PangoGlyphString it contains.
If pango_glyph_item_free() is missing and needs to be added, is it OK to 
free PangoGlyphItem , PangoItem and PangoGlyphString separately until then.
Regard,
Jeff Franks
