[cairo] [cairo-announce] cairomm release 1.7.0 (UNSTABLE) now available

[Jonathon Jongsma]

**********************
NOTE: This is an UNSTABLE release and contains MANY changes, including 
some API changes (in addition to the normal API additions and bugfixes). 
   I have provided justifications for the API changes below, so please 
read through them carefully and provide feedback if you disagree with 
any of them.  If you'd like to view the API documentation online as you 
read through the list of changes below, you can do so at

**********************

cairomm is a C++ API for the cairo graphics library.  For more
information, see http://cairographics.org/cairomm

A new cairomm release 1.7.0 is now available from:

WHAT'S NEW
==========

  * API Changes
    * ScaledFont: Change fontface constructor parameter to be a RefPtr
      * This is an API/ABI 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
