I don't remember off the top of my head what pango-view does.  At any rate,
which one you need really depends on what functionality you want.  hb-view
only works for one font, one script, one language, one direction at a time.
pango-view does not have any of these limitations, but does not let you choose
font by file, only by font descriptions.
