Overview of changes between 1.15.3 and 1.15.4
==============================================
General:
- Finish vertical text support.
- Fix various bugs that could cause ellipsization to stop prematurely.
- Fix rendering of background color being off in presence of rise attribute.
- Improved text-on-path example (examples/cairotwisted.c)

Win32 Improvements:
- Don't check for X and don't warn about missing fontconfig. [Tor Lillqvist]
- Automatically use -mms-bitfields on Windows when building with gcc. [Tor]
- Update makefile.msv. [Hans Breuer]

Code base cleanups:
- Whitespace cleanups.  Hopefully patches still apply using patch -l
- Replace C++-style // comments with C-style /* */ ones.
- Move the pango-view tool from examples/ into pango-view/.  The examples/
  dir is still available and for simple examples only.

Public API changes:

- New PangoLayout query functions:

	pango_layout_is_wrapped()
	pango_layout_is_ellipsized()
	pango_layout_get_unknown_glyphs_count()

  The is_wrapped and is_ellipsized functions return whether the layout
  had to wrap/ellipsize any paragraphs, as opposed to the get_wrap and
  get_ellipsize that return the wrap/ellipsize mode set.

- Misc new function:
	pango_parse_enum()

  This is more a convenience function for internal use, but set public
  to go with other pango_parse_* functions.  Bindings should feel free
  to ignore this.


- New header files:

  Moved gravity and matrix stuff into their own header files pango-gravity.h
  and pango-matrix.h.  Both are included from pango-types.h.

- Vertical text:

  New attribute types:

	PANGO_ATTR_GRAVITY
	PANGO_ATTR_GRAVITY_HINT.

  New enum type:

	PangoGravityHint

  New macro:

	PANGO_GRAVITY_IS_VERTICAL()

  New public functions:

	pango_attr_gravity_new()
	pango_attr_gravity_hint_new()
	pango_gravity_hint_get_type
	pango_context_set_gravity_hint()
	pango_context_get_gravity_hint()
	pango_gravity_get_for_matrix()
	pango_gravity_get_for_script()

  Removed:
	pango_matrix_to_gravity()

  replaced by pango_gravity_get_for_matrix()
  
  Gravity API added in previous releases:

	PangoGravity
        pango_gravity_get_type
        pango_context_get_base_gravity
        pango_context_get_gravity
        pango_context_set_base_gravity
	pango_font_description_get_gravity
	pango_font_description_set_gravity
	pango_gravity_to_rotation

  A tip on using the vertical text support: If you just want to get correct
  behavior in rotated labels (say, vertical Chinese/Japanese, but rotated
  Latin, etc), all you need to do is to set the context gravity to
  PANGO_GRAVITY_AUTO.  You can do this for example

	#if defined(PANGO_VERSION_CHECK) && PANGO_VERSION_CHECK(1,15,4)
	  pango_context_set_gravity (context, PANGO_GRAVITY_AUTO);
	#endif

Bugs fixed in this release:
	Bug 395328 – Map kATSDeletedGlyphcode to PANGO_GLYPH_EMPTY
	Bug 397337 – Use is_ellipsized and is_wrapped to optimize property
		     changes
	Bug 328585 – Need to know if a layout has unknown glyphs
		     Patch from LingNing Zhang
	Bug 326693 – PangoLayouts should be query-able about their
		     effective properties (width / wrapped / ellipsized / etc)
	Bug 397327 – pango-layout.c: 'pango_layout_is_ellipsized' must return
		     a value
	Bug 323173 – Add layout of mixed direction text for vertical layout
	Bug 394453 – Use -mms-bitfields
	Bug 392628 – Don't check for X on win32
