Overview of changes between 1.15.2 and 1.15.3
==============================================
- Fix Hangul crasher and other Hangul bugs introduced in 1.15.2
- Spell-checked docs
- Build fixes
- Don't introduce bitfields in public structs.  This changes some public API
  that was broken in the 1.15 series.  The new struct is backward compatible
  with the older Pango series, but not with earlier 1.15.x devel releases.

- New Public API:

  * PangoAnalysis.flags and PANGO_ANALYSIS_FLAGS_CENTERED_BASELINE.  These are
    mostly only useful for the vertical text support in Pango, but language
    bindings probably want to update their bindings for PangoAnalysis to
    include these.

  * New PangoMatrix methods:

	pango_matrix_transform_distance()
	pango_matrix_transform_point()
	pango_matrix_transform_rectangle()
	pango_matrix_transform_pixel_rectangle()

    The transform_rectangle methods are particularly useful when an
    app/toolkit wants to know the extents of a rotated layout in device
    coordinates.  It will be used by Gtk+ for example, and is used by the
    pango-view tool too.  The _pixel_ variant takes a PangoRectangle in device
    units instead of Pango units.

  * Unit conversion helpers:

	pango_units_from_double()
	pango_units_to_double()
	pango_extents_to_pixels()

    The first two just convert between Pango units (fixed precision) and
    double floating-point numbers.  The current implementations are as simple
    as "(int)floor (d * PANGO_SCALE + 0.5)" and "(double)i / PANGO_SCALE", but
    the idea is to have optimized versions of these that do not use the FPU in
    the future.  That will be appreciated by embedded devices without FPU
    units.  Since the functionality can be generally useful, the API is made
    public.

    The pango_extents_to_pixels() function in conjunction with
    pango_matrix_transform_rectangle() makes it possible to convert extents to
    device space and round then, instead of having to transform rounded
    user-space extents.
