Changes in 4.6.0
- the licenses used in all components of the core system have
been collected in the LICENSE file (Thanks to Peter Bex)
- Added new compiler option `-no-module-registration' which
omits generation of module registration code, even when
generation of import libraries has not been enabled
- running `chicken' without arguments now hints at the
existence of `csi' and `csc'
- `caar', `cdar' and `cddr' generate faster code
- calls to `list', `vector' and the internal structure
allocation primitive that take 1 to 8 arguments generate
faster code
- `chicken-install' now checks the version of the setup
configuration file `setup.defaults'
- added option `-exact' to `chicken-status' and `chicken-uninstall',
which treats the pattern argument as the literal name of the
extension to be listed/deinstalled
- `assert' shows line-number information, if available
(suggested by Alejandro Forero Cuervo)
- interpreted code records the lexical-environment at call-
sites, which can in case of an error be inspected with the
new `,c', `,f' and `,g' csi toplevel commands
- the evaluation-result history in `csi' can be inspected and
cleared (to reduce memory load) with the toplevel commands
`,h' and `,ch'
- unit `data-structures': deprecated `left-section' and
`right-section'
- fixed bug that caused the static syntax-environment of
syntax exported by a module to be incomplete
- module `setup-api': Documented the `version>=?' and
`extension-name-and-version' proceedures
- unit `posix': `utc-time->seconds' is considerably
faster on Mac OS X (thanks to Jim Ursetto);
added new procedure `file-type'
- the `time' macro now shows the correct number of minor
garbage collections
- the immediate-object check inside the marking procedure
of the garbage collector has been manually inlined which
results in a significant GC speedup, depending on memory
load
- unit `srfi-18' and `scheduler': various bugfixes (thanks
to Joerg Wittenberger)
- unit `srfi-4': bugfix in 8-bit vector allocation routines
(thanks to Kon Lovett)
- added `-:H' runtime option to dump heap state on exit
- fixed missing change in Makefile.cygwin (thanks to John Cowan)
- fixed bug in `let-optionals' macro that caused problems when the
rest-variable was actually named `rest' (thanks to Alejandro
Forero Cuervo)
- when Scheme files are translated to C++ or Objective-C, `csc'
will register the feature-identifiers `chicken-scheme-to-c++'/
`chicken-scheme-to-objc' ar compile-time
- fixed bug in expansion of `#!key' parameters in lambda-lists
- debug-output for forcing finalizers on exit goes to stderr now
(thanks to Joerg Wittenberger)
- the installation routines for extensions automatically add
version-number information if none is given in the extension
property list (suggested by Alejandro Forero Cuervo)
- `standard-extension' accepts `#f' now for the version number
and will use the version that has been obtained via
`chicken-install'
- `fifo?', `symbolic-link?', `directory?', `regular-file?', `socket?',
`character-device?' and `block-device?' now accepts file-descriptors
or filenames
- `find-files' takes keyword arguments, now (including the options
to process dotfiles and ignore symbolic links); the old argument
signature is still supported but deprecated
- removed dependency on `symbol-append' in some macros used in
srfi-4.scm to be able to compile the system with older chickens
- fixed bug in script that generates development snapshot
- added build-variable `TARGET_FEATURES', which can be used to pass
extra options enabling or disabling fetures for a system configured
for cross-compilation
- added compiler and interpreter option `-no-feature FEATURENAME' that
disables predefined feature identifiers
- code compiled with interrupts disabled will not emit inline files
for global inlining since they may execute in a context where
interrupts are enabled
- the `setup.defaults' file that holds download sources for
`chicken-install' now allows aliases for locations
- CHICKEN systems build from cross-compilation now by default
transparently build and install extensions for both the host
and target parts of the cross-compilation setup; the options
`-host' and `-target' can now be used to selectively build
an extensions for the host- and the target system, respectively
- also added `-host' and `-target' options to `chicken-status' and
`chicken-uninstall'
- `chicken-install' now respects the `http_proxy' environment variable
(contributed by Stephen Eilert)
- the `srfi-4' library unit has been heavily cleaned up and optimized
- optimization-level 3 now enables global inlining
- fixed the case that declarations listing global identifiers did not
correctly rename them
- deprecated `-N' option shortcut for `-no-usual-integrations' option in
`csc'
- `csi' now offers a toplevel command `,e' for invoking an external
editor (suggested by Oivind Binde)
- the `describe' command in `csi' now detects many circular lists
(contributed by Christian Kellermann)
- `csi' doesn't depend on the `srfi-69' library unit anymore
- when a closing sequence delimiter is missing or incorrect, the
reader also reports the starting line of the sequence
- the reader signals an error when a file contains certain characters
that indicate that it is a binary file
- procedure-information shown by the printer for procedures is now
corrected for some library procedures that where missing the correct
information; `getter-with-setter' copies procedure-information objects
into the newly created accessor procedure, if available
- calls to some known pure standard- or extended procedures are removed, if
the procedures are called with side-effect free arguments and the
result is not used (this can also by enabled for user procedures with
the `constant' declaration)
- fixed some build-system bugs related to installation
- fixed a problem in the C runtime code that prevented it to be compileable
without a configuration header-file
- the makefile-target to build a bootstrapping `chicken' executable
performs multi-stage build now
- changed error message when required extension is out of date (thanks to
Mario Goulart)
- documented library units loaded by default in `csi' (thanks to Moritz
Heidkamp)
- added `boot-chicken' makefile target to simplify bootstrapping
the system from sources and documented this in the README
(suggested by Jim Ursetto)
- CHICKEN can now be built on haiku (contributed by Chris Roberts)
- on Solaris, the system can be compiled with the SunPro C compiler
(thanks to Semih Cemiloglu)
- removed the `-disable-warnings' compiler option and `disable-warnings'
declaration specifier
- `fx/' and `fxmod' generate now faster code in safe mode
- cleaned up manual pages
- slightly optimized variable- and procedure-access
- in the compiler `-debug-level 2' implies `-scrutinize'
- internal compiler-transformation for `for-each' and `map'
apply now with any expression as the procedure argument
- the compiler warns about non-intrinsic exported toplevel variables
which are declared to be safe
- `csc' didn't handle the `-verbose' option (thanks to Mario Goulart)
- the `,d' command in `csi' now detects circular lists (thanks to
Christian Kellermann)
- strings passed to C runtime functions and which are converted to
0-terminated C strings are now checked for not containing embedded
`\0' characters (thanks to Peter Bex)
- errors in user-defined record printers are caught and shown in the
output instead of throwing an error to avoid endless recursion when
an error message is printed
- a feature identifier named `chicken-MAJOR.MINOR' is now defined
to simplify conditionalization of code on the CHICKEN version
- `getter-with-setter' copies the lambda-information (if available) from
the getter to the generated procedure
- `time' uses a somewhat more concise output format and outputs timing
information to stderr instead of stdout
- added a new chapter on cross-development to the manual
- added the `safe-globals' declaration specifier
- split up manual chapter `Modules and macros' into two chapters
(named `Modules' and `Macros', respectively - suggested by
Mario Goulart)
- the last 5 non-precompiled regular expressions are now internally
cached in compiled form, which speeds up repeated matching of
the same uncompiled regular expression dramatically
- added the new procedure `yes-or-no?' to the `utils' library unit
- added a `bench' makefile target that runs some non-trivial
benchmark programs
- added `install-target' and `install-dev' makefile target for
installing only target system libraries in cross-mode and
development files (static libraries and headers)
- added `[-]no-procedure-checks-for-toplevel-bindings' compiler
option and declaration
- usage of unimported syntax in modules gives more usable
error messages; in particular, used but unimported FFI forms are
now detected
- invalid syntactic forms (mostly `()') encountered by the compiler
or interpreter show the contextual form containing the expression,
or, if indicated by the context warns about missing imports
- simplified manual pages of all core tools - they now refer to
the output shown by invoking `<tool> -help'
- added new option `-feature FEATURE' to `chicken-install' tool
to pass feature-identifiers to invocations of `csc'
- removed deprecated `-host-extension' option from `chicken-install'
- `chicken-status' in a system built for cross-compilation now
lists extensions installed in the target prefix, unless the
new `-host' option is given on the command line
- `chicken-uninstall' in a system built for cross-compilation now
removes extensions installed in the target prefix, unless the
new `-host' option is given on the command line
- added missing entry for `finite?' to the `chicken' module
exports
- added new procedure `port-closed?' to the `library' unit
(contributed by Peter Bex)
- added new procedure `symbol-append' to the library unit
- the compiler-option `-optimize-level 0' is equivalent to
`-no-compiler-syntax -no-usual-integrations`
- internal rewritings of `map' and `for-each' ensure correct
evaluation order of the arguments and does a better job
at detecting non-list arguments (thanks to Jim Ursetto)
- `void' now takes arbitrary arguments and ignores them
- deprecated `noop' (from the `data-structures' unit) which
is now replaced by `void'
- the `time' macro now performs a major garbage collection
before executing the contained expressions and writes
the timings in a more compact format to the port given
by `(current-error-port)' instead of the standard output
port
- definitions of the form `(define define ...)' and
`(define-syntax define-syntax ...)' now trigger an error,
as required by R5RS (thanks to Jeronimo Pellegrini and Alex
Shinn)
- deprecated `random-seed' from the `extras' unit, since it
is identical to `randomize'
- added new procedure `create-temporary-directory' to the
`files' unit
- deprecated the optional path separator argument to
`make-pathname'
- slightly improved the performance of keyword argument
processing
- removed the deprecated `canonical-path' and `current-environment'
procedures from the `posix' unit
- warnings that mostly refer to programming style issues are
now coined `notes' and are only shown in the interpreter
or when debug-mode is enabled or when scrutiny is enabled
when compiling

Release 1.10.0 (2010-09-06 Chris Wilson <chris@chris-wilson.co.uk>)
===================================================================
The cairo community is astounded (and flabbergast) to finally announce
the 1.10.0 release of the cairo graphics library. This is a major update
to cairo, with new features and enhanced functionality which maintains
compatibility for applications written using any previous major cairo
release, (1.8, 1.6, 1.4, 1.2, or 1.0). We recommend that anybody using
a previous version of cairo upgrade to cairo 1.10.0.
One of the more interesting departures for cairo for this release is the
inclusion of a tracing utility, cairo-trace. cairo-trace generates a
human-readable, replayable, compact representation of the sequences of
drawing commands made by an application. This can be used to inspecting
applications to understand issues and as a means for profiling
real-world usage of cairo.
The traces generated by cairo-trace have been collected in
git://git.cairographics.org/git/cairo-traces
and have driven the performance tuning of cairo over the last couple of
years. In particular, the image backend is much faster with a new
polygon rasterisation and a complete overhaul of the tessellator. Not
only is this faster, but also eliminates visual artifacts from
self-intersecting strokes. Not only has cairo-trace been driving
performance improvements within cairo, but as a repeatable means of
driving complex graphics it has been used to tune OpenGL, DDX, and
pixman.
Cairo's API has been extended to better support printing, notably
through the ability to include a single compressed representation of an
image for patterns used throughout a document, leading to dramatic file
size reductions. Also the meta-surface used to record the vector
commands compromising a drawing sequence is now exposed as a
CAIRO_SURFACE_TYPE_RECORDING, along with a new surface that is a child of a
larger surface, CAIRO_SURFACE_TYPE_SUBSURFACE. One typical usage of a
subsurface would be as a source glyph in a texture atlas, or as a
restricted subwindow within a canvas.
Cairo's API has also resurrected the RGB16 format from the past as
the prevalence of 16-bit framebuffers has not diminished and is a
fore-taste of the extended format support we anticipate in the future.
Increasing cairo's utility, we introduce the cairo_region_t for handling
sets of pixel aligned rectangles commonly used in graphics applications.
This is a merger of the GdkRegion and the pixman_region_t, hopefully
providing the utility of the former with the speed of the latter.
Furthermore cairo has been reworked to interoperate more closely with
various acceleration architectures, gaining the ability to share
those hardware resources through the new cairo_device_t. For instance,
with the new OpenGL backend that supersedes the Glitz backend, hardware
and rendering operations can be shared between a classic OpenGL
application mixing libVA for the hardware assisted video decode with
cairo for high quality overlays all within the same OpenGL canvas.
Many thanks for the hard work of Adrian Johnson, Andrea Canciani, Behdad
Esfahbod, Benjamin Otte, Carl Worth, Carlos Garcia Campos, Chris Wilson,
Eric Anholt, Jeff Muizelaar, Karl Tomlinson, M Joonas Pihlaja, Søren
Sandmann Pedersen and many others that have contributed over the last
couple of years to cairo. Thank you all!
Snapshot 1.9.14 (2010-07-26)
============================
A quiet couple of weeks, hopefully Cairo is seeing widescale deployment and
we are being to see the results of the stabilisation effort. Clipping bugs
seems to have been the order of the last couple of weeks, with a couple
reported and duly fixed. Thank you Igor Nikitin and Karl Tomlinsion for
finding those regressions. At this point all that seems to remain to do is
to fix the outstanding regressions in the PDF backend...
Bugs fixes

https://bugs.freedesktop.org/show_bug.cgi?id=29125
Snapshot 1.9.12 (2010-07-12)
============================
A couple of weeks spent fixing those annoying bugs and cleaning up the build
system; the list of outstanding tasks to complete for the stable release is
finally shrinking. The chief bug fixer has been Benjamin Otte who not only
made sure that the public API is consistent and being tested for its
consistency, but also ensured that the documentation was up-to-date and
spent time clarifying cases where even the Cairo developers have come
unstuck in the past. Many thanks, Benjamin. However, he was not alone,
as Andrea Canciani continued his fine work in isolating broken corner cases
and proceeding to fix them, and tidying up the quartz backend. And last, but
definitely not least, M Joonas Pihlaja tried building Cairo across a
perverse range of systems and fixed up all the loose bits of code that came
unravelled. Thanks everybody!
API Changes
-----------
cairo_surface_set_mime_data, cairo_surface_get_mime_data:
The length parameter is now an unsigned long (as opposed to an unsigned
int). The parameter is intended to be an equivalent to a size_t without
requiring POSIX types and be large enough to store the size of the
largest possible allocation.
cairo_gl_surface_create_for_texture:
This a new surface constructor for cairo-gl that explicitly enables
render-to-texture for foreign, i.e. application, textures.
cairo_region_xor, cairo_region_xor_rectangle
A couple of utility routines add to the region handling interface for
the purpose of replacing existing GdkRegion functionality.
Bugs fixes
----------
https://bugs.launchpad.net/ubuntu/+source/cairo/+bug/600622
Inkscape was caught in the act of attempting to modify a finished surface.
Unfortunately, we had the ordering of our guards and assertions wrong and
so an ordinary application error was triggering an assert in Cairo. This
lead Benjamin to add a test case to ensure that the entire public API
could handle erroneous input and then proceeded to fix a whole slew of
uncovered bugs.
https://bugs.freedesktop.org/show_bug.cgi?id=28888
A regression introduced by the special casing of uploading images to an
xlib surface in-place which was ignoring the translation applied to the
image.
Snapshot 1.9.10 (2010-06-26)
============================
The first "quick" snapshot in the run up to the stable release. The
last snapshot was picked up by the bleeding edge distributions and so the
bug reports have to started to roll in. The most frequent of these are the
introduction of rendering errors by applications that modify a surface
without subsequently calling cairo_surface_mark_dirty(). Make sure the
application developers are aware of increased reliance on strict use of the
Cairo API before 1.10 is released!
The usual slew of bugs reported and we would like to thank Zoxc for
contributing the WGL interface for cairo-gl, and finding more build
failures on win32. And it just wouldn't be a 1.9 snapshot unless
Benjamin Otte improved the error handling within cairo-gl, as well as
isolating and fixing some more errors in the test suite. The biggest bug of
the snapshot turned out to be a major sign extension issue that had lain
hidden for many years and was suddenly exposed by incorrectly rounding
rectangles when performing non-antialiased rendering. Also to the relief
of many we have included the downstream patch to honour the user's LCD
filtering preferences for subpixel rendering of fonts. The interface
remains private for the time being, whilst the proposed public API is
finalized.
API changes
-----------
None.
Snapshot 1.9.8 (2010-06-12)
===========================
One major API changes since the last snapshot, and a whole slew of bugs
fixed and inconsistencies eliminated. Far too many bugs fixed to
individually identify. We need to thank Benjamin Otte for his fantastic
work on the cairo-gl backend making it faster and more robust, Andrea
Canciani for finding so many bugs and developing test cases for them, as
well fixing them. And last but not least we must all thank Adrian Johnson for
continuing to eliminate bugs and improving the PostScript and PDF backends.
This snapshot represents almost 4 months of bug fixing, bringing Cairo to
a point where we consider it almost ready to be a candidate for release.
There are a few known bugs left to be fixed, being tracked in
https://bugs.freedesktop.org/show_bug.cgi?id=24384, so please give Cairo a
whirl and report any regressions. The plan is to release a new snapshot
every other week leading to a 1.10 release with a target date of
2010-08-16.
API additions
-------------
CAIRO_FORMAT_RGB16_565
16 bit devices still remain popular, and so with great demand,
CAIRO_FORMAT_RGB16_565 has been restored enabling applications to create
and use 16 bit images as sources and render targets.
cairo_surface_create_for_rectangle()
It is common practice to cut an image up into many smaller pieces and use
each of those as a source - a technique called texture atlasing.
cairo_surface_create_for_rectangle() extends Cairo to directly support use
of these subregions of another cairo_surface_t both as a source and as a
render target.
cairo_region_create()
cairo_region_create_rectangle()
cairo_region_create_rectangles()
cairo_region_copy()
cairo_region_reference()
cairo_region_destroy()
cairo_region_equal()
cairo_region_status()
cairo_region_get_extents()
cairo_region_num_rectangles()
cairo_region_get_rectangle()
cairo_region_is_empty()
cairo_region_contains_rectangle()
cairo_region_contains_point()
cairo_region_translate()
cairo_region_subtract()
cairo_region_subtract_rectangle()
cairo_region_intersect()
cairo_region_intersect_rectangle()
cairo_region_union()
cairo_region_union_rectangle()
The Cairo region API was actually added a couple of snapshots ago, but we
forgot to mention it at the time. A simple API for the handling of
rectangular pixel-aligned regions by Soeren Sandmann.
Backend-specific improvements
-----------------------------
cairo-gl
Benjamin Otte made more than 200 commits in which he refactored the cairo-gl
backend, reducing a lot of code duplication and enabled him to begin working
on improving performance by reducing state changes and associated overhead.
cairo-xlib
Access to the underlying connection to the Display is now thread-safe
enabling cairo-xlib to be used in a multi-threaded application without fear
of random corruption. Thanks Benjamin Otte!
cairo-xlib will now attempt to use PolyModeImprecise when compositing
trapezoids (i.e. a fill or a stroke operation with a non-trivial path) which
should allow hardware drivers more scope for accelerating the operation at
the cost of potentially incurring minute rendering errors. The mode can be
forced back to PolyModePrecise by setting the antialias parameter to
CAIRO_ANTIALIAS_SUBPIXEL.
cairo-svg
A notable improvement was contributed by Alexander Shulgin to enable SVG to
reference external image through the use an extended MIME data type.
Snapshot 1.9.6 (2010-02-19)
===========================
API additions
-------------
Add cairo_device_t
The device is a generic method for accessing the underlying interface
with the native graphics subsystem, typically the X connection or
perhaps the GL context. By exposing a cairo_device_t on a surface and
its various methods we enable finer control over interoperability with
external interactions of the device by applications. The use case in
mind is, for example, a multi-threaded gstreamer which needs to serialise
its own direct access to the device along with Cairo's across many
threads.
Secondly, the cairo_device_t is a unifying API for the mismash of
backend specific methods for controlling creation of surfaces with
explicit devices and a convenient hook for debugging and introspection.
The principal components of the API are the memory management of:
cairo_device_reference(),
cairo_device_finish() and
cairo_device_destroy();
along with a pair of routines for serialising interaction:
cairo_device_acquire() and
cairo_device_release()
and a method to flush any outstanding accesses:
cairo_device_flush().
The device for a particular surface may be retrieved using:
cairo_surface_get_device().
The device returned is owned by the surface.
API changes (to API new in the cairo 1.9.x series)
--------------------------------------------------
cairo_recording_surface_create()
cairo_recording_surface_ink_extents()
These are the replacement names for the functions previously named
cairo_meta_surface_create and cairo_meta_surface_ink_extents.
cairo_surface_set_mime_data
This interface is now changed such that the MIME data will be
detached if the surface is modified at all. This guarantees that
the MIME data will not become out of synch due to surface
modifications, and also means that for the MIME data to be useful,
it must be set after all modifications to the surface are
complete.
API removal (of experiment API)
-------------------------------
The cairo-glitz backend is removed entirely, (in favor of the new
cairo-gl backend). See below for more on cairo-gl.
Generic fixes
-------------
Many improvements for drawing of dashed strokes
Fix incorrect handling of negative offset
Faster computation of first dash (avoids near-infinite looping)
Approximate extremely fine dash patterns with appropriate alpha value
Optimize spans-based renderers for repeated rows, (such as in a rounded rectangle)
Backend-specific improvements
-----------------------------
cairo-drm
This is a new, direct-rendering backend that supports Intel graphics
chipsets in the i915 and i965 families. It's still experimental and
will likely remain that way for a while. It's already got extremely
good performance on the hardware it supports, so if nothing else
provides a working proof and performance target for the cairo-gl
work for Intel graphics.
cairo-gl
Start using GLSL to accelerate many operations. Many thanks to Eric
Anholt and T. Zachary Laine for this work. For the first time, we
have what looks like what will be a very compelling OpenGL-based
backend for cairo (in terms of both quality and performance).
See this writeup from Eric for more details on recent progress of
cairo-gl (which he presented at FOSDEM 2010):
http://anholt.livejournal.com/42146.html
cairo-image
The image backend is made dramatically faster (3-5 times faster for
benchmarks consisting primarily of glyph rendering).
cairo-quartz fixes:
Many fixes from Robert O'Callahan and Andrea Canciani including:
Fixed gradient pattern painting
Improved A8 image handling
Fixes for "unbounded" and other compositing operators
cairo-pdf fixes:
Improvements to embedding of JPEG and JPEG2000 data.
cairo-ps fixes:
Fix printing of rotated user fonts.
Snapshot 1.9.4 (2009-10-15)
===========================
API additions:
cairo_meta_surface_create()
cairo_meta_surface_ink_extents()
Finally exporting the internal meta-surface so that applications
have a method to record and replay a sequence of drawing commands.
cairo_in_clip()
Determines whether a given point is inside the current clip.
??? Should this be called cairo_in_paint() instead? in-clip is the test
that is performed, but in-paint would be similar to in-fill and in-stroke.
New utilities:
cairo-test-trace
A companion to cairo-perf-trace, this utility replays a trace against
multiple targets in parallel and looks for differences in the output,
and then records any drawing commands that cause a failure.
Future plans:
Further minimisation of the fail trace using "delta debugging".
More control over test/reference targets.
Backend improvements:
xlib
Server-side gradients. The theory is that we can offload computation
of gradients to the GPU and avoid pushing large images over the
connection. Even if the driver has to fallback and use pixman to render
a temporary source, it should be able to do so in a more efficient manner
than Cairo itself. However, cairo-perf suggests otherwise:
On tiny, Celeron/i915:
before: firefox-20090601 211.585
after: firefox-20090601 270.939
and on tiger, CoreDuo/nvidia:
before: firefox-20090601 70.143
after: firefox-20090601 87.326
In particular, looking at tiny:
xlib-rgba paint-with-alpha_linear-rgba_over-512 47.11 (47.16 0.05%) -> 123.42 (123.72 0.13%): 2.62x slowdown

inclusion by Pierre Tardy.
OpenGL - An advanced OpenGL compositor. The aim is to write a integrate
directed rendering using OpenGL at a high-level into Cairo. In
contrast to the previous attempt using Glitz which tried to
implement the RENDER protocol on top of OpenGL, using the
high-level interface should permit greater flexibility and
more offloading onto the GPU.
The initial work on the backend was performed by Eric Anholt.
Long standing bugs fixed:
Self-intersecting strokes.
A long standing bug where the coverage from overlapping semi-opaque
strokes (including neighbouring edges) was simply summed in lieu of
a costly global calculation has been fixed (by performing the costly
global calculation!) In order to mitigate the extra cost, the
tessellator has been overhauled and tune, which handles the fallback
for when we are unable to use the new span rasteriser on the stroke
(e.g. when using the current RENDER protocol). The large number of
pixel artefacts that implementing self-intersection elimination
removes is ample justification for the potential performance
regression. If you unfortunately do suffer a substantial performance
regression in your application, please consider obtaining a
cairo-trace and submitting it to us for analysis and inclusion into
our performance suite.

Snapshot 1.9.2 (2009-06-12)
===========================
API additions:
cairo_surface_set_mime_data()
cairo_surface_get_mime_data()
Should this take unsigned int, unsigned long or size_t for the length
parameter? (Some datasets may be >4GiB in size.)
Associate an alternate, compressed, representation for a surface.
Currently:
"image/jp2" (JPEG2000) is understood by PDF >= 1.5
"image/jpeg" is understood by PDF,PS,SVG,win32-printing.
"image/png" is understood by SVG.
cairo_pdf_version_t
cairo_pdf_surface_restrict_to_version()
cairo_pdf_get_versions()
cairo_pdf_version_to_string()
Similar to restrict to version and level found in SVG and PS,
these limit the features used in the output to comply with the PDF
specification for that version.
CAIRO_STATUS_INVALID_SIZE
Indicates that the request surface size is not supported by the
backend. This generally indicates that the request is too large.
CAIRO_STATUS_USER_FONT_NOT_IMPLEMENTED
Indicates that a required callback for a user-font was not implemented.
CAIRO_STATUS_LAST_STATUS
This is a special value to indicate the number of status values enumerated
at compile time. (This may differ to the number known at run-time.)
The built-in twin font is now called "@cairo:" and supports a limited set
of options like "@cairo:mono". Where are these specified?
cairo_in_fill() now uses HTML Canvas semantics, all edges are inside.
New experimental backends:
CairoScript
New utility:
cairo-trace and cairo-perf-trace
cairo-trace generates a human-readable, replayable, compact(-ish!)
representation of the sequences of drawing commands made by an
application.
Under the util/cairo-script directory is a library to replay traces.
perf/cairo-perf-trace replays traces against multiple backends
and makes useful benchmark reports. This is integrated with
'make perf'. You may collect your own traces or take advantage
of traces collected by the community:
git://git.cairographics.org/git/cairo-traces
(Put this into perf/cairo-traces to run these as part of "make perf".)
There is additional WIP in building a debugging tool for cairo applications
based on CairoScript (currently very preliminary, mostly serves to show
that GtkSourceView is too slow) :
people.freedesktop.org:~ickle/sphinx
Test suite overhaul:
The test suite is undergoing an overhaul, primarily to improve its speed
and utility. (Expect more changes in the near future to improve XFAIL
handling.)
Optimisations:
polygon rasterisation! Joonas implemented the Tor polygon scan converter,
on typical geometry is about 30% faster for the image backend.
Bovine Polaroids! For those not in on the joke, this is the long
awaited "copy-on-write snapshot" or "COW snapshot" support. The
user-visible feature is that including the same image multiple times
into a PDF file should result in only a single instance of that
image in the final output. This is unlike previous versions of cairo
which would generate very large PDF files with multiple copies of
the same image. Adrian says that the PDF is not quite working as
well as it should yet, so we hope for futher improvements before
cairo 1.10.
Bug fixes:
EXTEND_PAD.
Better handling of large scale-factors on image patterns.
Emit /Interpolate for PS,PDF images.
Global glyph cache - cap on the total number of inactive glyphs,
should prove fairer for fonts with larger glyph sets.
Compilation without fontconfig
Improved handling of low-bitdepth sources (e.g. copying the contents
of 16-bit xserver windows)
Regressions:
cairo_traps_extract_region >10x slower. Fix pending.
Still to come:
Region tracking API (ssp) for damage tracking, hit testing etc
mime-surface
An expiremental OpenGL backend?
Tweaks to tessellator, allocations of patterns, delayed
initialisation of the xlib backend (reduce the cairo overhead of
render_bench by ~80%).

--- 4.0.12 2010/08/17
Z39.50 facet support. Facet specifications are passed for search in
other-information with ASN.1 as defined in facet.asn and OID
.10.1000.81.5 . Facets are expressed as an Attribute list as known
from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
3 is limit (number of entries to get in response). yaz-ztest returns
dummy facets if a client asks for them.
