Update to 1.8.0:

1.8.0:

* No notable changes since 1.7.2

1.7.2 (UNSTABLE):

* API Changes (all API changes are in unstable API introduced in 1.7.x)
  * UserFontFace is not implemented with virtual functions rather than by
    registering callbacks
  * Cairo::scaled_matrix() -> Cairo::scaling_matrix() to match other matrix
    convenience functions
* Bugfixes
  * Incorrect refcounting on ScaledFont
  * build fixes for Mac OSX
* Contributors for this release:
     1	Armin Burgmeier

1.7.0 (UNSTABLE):

 * API Changes
   * ScaledFont: Change fontface constructor parameter to be a RefPtr
     * This is an API break, but the old interface was essentially unusably
       broken
   * Cairo::Matrix now inherits from cairo_matrix_t
     * Previously, we had used Cairo::Matrix throughout our API, but
       Cairo::Matrix was just a typedef for cairo_matrix_t
     * This could be considered an API change, but the new Cairo::Matrix still
       is-a cairo_matrix_t even if it's not exactly a cairo_matrix_t.  This
       change does not break ABI either, as there are no data members or virtual
       functions.  So I believe this is a safe change, but feedback is appreciated.
     * Provides a much more C++-friendly API for handling matrices
     * Also added a set of standalone 'generator' functions for generating
       starting matrices:
       * Cairo::identity_matrix(), rotation_matrix(), translation_matrix(),
         scaled_matrix().  This allows for convenient use such as:
           cr->set_matrix(Cairo::identity_matrix());
         rather than something like what was required before:
           Cairo::Matrix identity_matrix;
           cairo_matrix_init_identity(&identity_matrix);
           cr->set_matrix(identity_matrix);
   * Pattern: get/set_matrix() functions were using a cairo_matrix_t parameter in
     the API.  This is the only place where we used this type and so it was
     inconsistent with every other matrix-related API in cairomm.  Previously
     this wasn't really an issue since cairo_matrix_t and Cairo::Matrix were
     typedefed to the same type.  However, with the the change to Cairo::Matrix
     mentioned above, this because a much bigger issue.
     * This is an ABI-compatible change, but it is a minor API change that could
       result in some warnings or compile problems in some situations`
 * New API (some of these are new in cairo 1.8, some are older API that were
   not wrapped in cairomm previously)
   * Add Context::get/set_scaled_font()
   * add Context::show_text_glyphs()
   * add Context::get_font_options()
   * Add Surface::has_show_text_glyphs()
   * Add Surface::get_content() + test
   * Added Surface::get_fallback_resolution()
   * Add ScaledFont::text_to_glyphs()
   * Add PsSurface::get_eps()
   * Add missing Win32Surface API: create_with_ddb(), create_with_dib(), and get_image()
   * Add Win32PrintingSurface
   * Vastly improved font support
     * ToyFontFace
     * UserFontFace
     * Add Freetype font support (FtFontFace, etc)
     * Add win32 font support (Win32FontFace, etc)
     * Add quartz font support (QuartzFontFace, etc)
     * Add ScaledFont::get_scale_matrix()
 * Fix API inconsistencies by adding overloads and deprecating old versions
   * Deprecated FontFace::extents() in favor of FontFace::get_extents()
   * Deprecated FontFace::text_extents() in favor of FontFace::get_text_extents()
   * Deprecated FontFace::glyph_extents() in favor of FontFace::get_glyph_extents()
   * Add sigc::slot versions of all of the functions that take a
     cairo_write_func_t or cairo_read_func_t
     * This adds a new dependency on libsigc++, but offers a much more flexible
       and C++-like solution
     * Old API using cairo_write_func_t / cairo_read_func_t still exist, but are
       deprecated in favor of the new API
   * Add a default value for the font_options parameter of the ScaledFont constructor
 * Added new macros for determining library version:
   * CAIROMM_MAJOR_VERSION, CAIROMM_MINOR_VERSION, and CAIROMM_MICRO_VERSION
 * Add a bunch of extra .pc files for additional functionality
   * like cairo, create convenience .pc files for using some of the optional
     features.  For example, cairomm-ft-1.0, cairomm-pdf-1.0, cairomm-xlib-1.0, etc.
 * Numerous windows build improvements
 * Added a *lot* of automated tests
