Support glyph clusters of multiple glyphs
Sometimes a glyph cluster resolves to multiple glyphs, for example when
diacritics are used with Arabic script. This doesn't map well to the
list of glyphs expected by libass.
Extend the glyph list to a list of singly-linked glyph clusters of
glyphs and adapt the renderer to support this.
