This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

* No notable changes since 1.7.2
1.7.2 (UNSTABLE):

registering callbacks
* Cairo::scaled_matrix() -> Cairo::scaling_matrix() to match other matrix
convenience functions
* Bugfixes

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
* Windows build: Fix the build on the freely available Visual Studio Express
compiler.
Changes 1.6.2:
* Fix build on OSX when both Quartz and Xlib surfaces are enabled
* Fixed a bug where an exception message would often report "Success" when it
should have reported an error message
* Added ability to get the error status code from an exception:
Cairo::logic_error::get_status_code()
* Added new elements to the surface type enumeration
* wrap cairo_format_stride_for_width(). All new cairo 1.6 API should now be
implemented in cairomm
Changes 1.5.0:
* Unstable release wrapping new API in cairo 1.5 series
* Bugfixes
* Added the --enable-api-exceptions=yes/no configure option, to allow
cairomm to build when exceptions are disabled. For instance, when
using CXXFLAGS=-fno-exceptions with g++.
Changes 1.4.2:
* Bugfixes:
Changes 1.4.0:
* Wrapped new API added in cairo 1.4
* Added support for Quartz surfaces
* ability to use dynamic casting for surfaces and patterns returned from
Context::get_target(), Context::get_source(), etc.
* Various build and bug fixes
