Overview of changes between 1.15.1 and 1.15.2
==============================================
* Engines:
  - Improved Hangul shaper engine
  - Improved Indic shaper and language engines
  - Require libthai >= 0.1.7 for the Thai language engine

* Optimizations:
  - Avoid some floating-point operations.  Should cut the number of float
    ops per expose event in pangocairo to a half.
  - Cache ink and logical extents for PangoLayout

* New Public API:

  - New, generated, public header file pango-features.h.  Included by
    pango.h.  Currently contains the version information.  In the future,
    can be expanded to define which backends have been enabled, etc.

  - Public macros and functions for compile- and run-time version checking:

	PANGO_VERSION_ENCODE()
	PANGO_VERSION_MAJOR
	PANGO_VERSION_MINOR
	PANGO_VERSION_MICRO
	PANGO_VERSION
	PANGO_VERSION_STRING
	PANGO_VERSION_CHECK()
	pango_version()
	pango_version_string()
	pango_version_check()

    The scheme chosen here is a mixture of approaches taken by glib and cairo.
    The advantage over the glib model is that there are no public variables,
    but it still gives access to a string and numerical representation of the
    version number at compile- and run-time.
    
    The macros enable conditional compilation of code depending on newer Pango
    APIs, while the runtime functions allow refusing to run against old
    versions of the library.

  - New, readonly, version of methods that give read/write access to the
    internals of PangoLayout:

	pango_layout_get_line_readonly()
	pango_layout_get_lines_readonly()
	pango_layout_iter_get_line_readonly()
	pango_layout_iter_get_run_readonly()

    These should be used when you do not intend to modify the run/line,
    which is most of the time the case.  The only exception known to me
    is Firefox that adjusts glyph widths to do justification.  Most other
    uses that do not write to the returned structs (or structs accessible from
    them) should be ported to the new readonly API to benefit from major
    optimizations (in this case, line extents caching).  The list includes,
    but is not limited to, Gtk+, SWT, ClassPath, gnome-applets, libgnomeprint,
    xmlroff, GtkMathView, Conglomerate, Dia, Anjuta, wxWindows, The Gimp, 
    and various other applications/libraries:

      http://www.google.com/codesearch?hl=en&q=+pango_layout_(iter_)%3Fget_(lines%3F%7Crun)%5B%5E_%5D&start=50&sa=N

    Worth noting here is that, many uses of pango_layout_get_lines() can be
    replaced by a pango_layout_get_iter() that works both more elegantly and
    more efficiently.  The versioning macros introduced in this release can be
    used to make code use these new symbols without breaking compilation
    against older Pango (though, such code compiled with the new Pango cannot
    be run against an older Pango).

  - pango_language_get_default(): Note that, this does not make Pango
    fallback to the default language automatically (yet), but the user can
    use this function to set the default language of the locale on a context:

	  pango_context_set_language (context, pango_language_get_default());

    This essentially deprecates gtk_get_default_language().  The pango-view
    tool has been updated to use this feature, so it now respects $LANG when
    choosing fonts.

  - pango_color_to_string().

		     as I would expect
