Overview of changes between 1.16.4 and 1.17.0
==============================================

General:

- Text justification.  A simple justification algorithm is implemented
  that tries to justify by expanding spaces in the line, and if none
  found, by adjust letter spacing.  [Based on patch by Mathias
  Hasselmann]

- The pango_script_get_sample_language() function is modified to use
  the value of environment variables PANGO_LANGUAGE or LANGUAGE
  (checked in that order) to make guess better languages for scripts.
  The env var should be a list of language tags, like "en:fa" for
  example where in effect makes Pango choose Persian (fa) fonts
  instead of Arabic (ar) fonts when a run of text in the Arabic script
  is found in an otherwise non-Arabic layout.

  This trick is also useful for East Asian languages.  For example a
  Japanese user that cannot set her primary language to Japanese can
  still set PANGO_LANGUAGE="ja" and Pango will map CJK characters to
  Japanese.

  The LANGUAGE env var is a standard gettext variable listing
  languages the user wants to receive UI translated messages in.
  However, since most packages don't provide separate English
  translations, setting LANGUAGE="en:ja" doesn't have the intended
  effect and UI messages will be shown in Japanese.  For these
  situations one can use LANGUAGE="en:C:ja".  Pango skips the special
  language tag 'C'.

- Simplified embedded-shape rendering with pangocairo backends do.
  [Richard Hult]

- New header file: Moved PangoLanguage APIs into its own header
  pango-language.h, which is included from pango-types.h.

- ATSUI backend now lists synthesized italic faces like other

- Misc optimizations and fixes.

OpenType Layout Engine Improvements:

- Vertical glyph variants are not selected in vertical text if the
  font supports them.

- Instead of hardcoded OpenType script tag in each module, and using
  Default Language System unconditionally, Pango will now find and use
  the script/lang-sys pair that best matches the detected script and
  language of a run of text.  Moreover, it also applies the OpenType
  'locl' feature.
  
  These, plus the PANGO_LANGUAGE env var, give font designers and
  users lots of options to provide/choose language-specific glyph
  variants.
  
  Only basic, arabic, and syriac modules updated to take advantage of
  the new support so far.

New pango-view command line options:

	--align
	--justify
	--language

Public API Changes:

- New public pangocairo API:

	PangoCairoShapeRendererFunc
	pango_cairo_context_set_shape_renderer() 
	pango_cairo_context_get_shape_renderer() 

  These are used by the default pangocairo renderer to render shape
  attributes (see examples/cairoshape.c).  Cairo-based PangoRenderer
  implementations outside Pango may want to implement the draw_shape()
  method similarly to provide compatibility with these new APIs.  (See
  bug #437533 for GdkPangoRenderer for example.)

- Other public API changes:

	New is_expandable_space member in PangoLogAttr
	New macro PANGO_UNITS_ROUND()

- New OpenType engine API.  These are engine API, for use by Pango
  modules, and typically need not to be bound by language bindings:

	PANGO_OT_NO_FEATURE
	PANGO_OT_NO_SCRIPT
	PANGO_OT_TAG_DEFAULT_SCRIPT
	PANGO_OT_TAG_DEFAULT_LANGUAGE
	PangoOTFeatureMap
	PangoOTRulesetDescription
	pango_ot_ruleset_get_for()
	pango_ot_ruleset_new_for()
	pango_ot_ruleset_maybe_add_feature()
	pango_ot_ruleset_maybe_add_features()
	pango_ot_ruleset_description_hash()
	pango_ot_ruleset_description_equal()
	pango_ot_ruleset_description_copy()
	pango_ot_ruleset_description_free()
	pango_ot_tag_from_script()
	pango_ot_tag_to_script()
	pango_ot_tag_from_language()
	pango_ot_tag_to_language()

	Bug 64538 – pango_layout_set_justify() doesn't work
