graphics/cairo: revert bfd option again, nia disabled that already

Sorry for not noticing that my patch conflicted with the Makefile
change that added --disable-symbol-lookup already. It is a fringe
feature that we really don't need.

graphics/cairo: make symbol lookup feature optional, avoiding libbfd

If cairo finds libbfd, it would use it unless symbol lookup was not
requested. This dependency is problematic as the binutils library
does not provide long-term ABI stability. We can live fine without this
feature and reduce the dependency footprint.

Bring back previous patch in correct version to fix SHM part of
build on NetBSD-5 with native Xorg.

Additionally, disable GL support since NetBSD-5's MesaLib is too old and,
according to upstream, cairo-gl "is only really being experimented
with currently by toy applications".

Increase the minium required version of the "x11/libxcb" package to 1.6.
There are at least two packages ("graphics/cairo" and "x11/xlsclients")
which require this. And we definitely want to avoid the situation where
both the based and "pkgsrc" version get used at the same time.

Bump all the packages which use the "x11/libxcb" package except the two
which already require version 1.6. For those package remove the manually
set minimum required version.

Change discussed with Thomas Klausner in private e-mail.

Update to 1.10.0. Add default-on xcb option (implying x11 option).

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...

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
     
     xlib-rgba paint-with-alpha_linear3-rgba_over-512   47.27 (47.32 0.04%) -> 123.78 (124.04 0.13%):  2.62x slowdown
     


New experimental backends:

   QT

   OpenVG - The initial work was done by yvind Kolås, and made ready for
            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%).

Update to 1.4.12:

Release 1.4.12 (2007-11-26 Carl Worth <cworth@cworth.org>)
==========================================================
This is the sixth update in cairo's stable 1.4 series. It comes five
months after the 1.4.10 release. This fix includes various bug fixes
originally developed during the 1.5.x development and backported to
1.4.

Some of the most significant bug fixes prevent crashes:

  * Avoid overflow when allocating large buffers (Vladimir Vukicevic)

  * Fix crash with cairo_pattern_set_user_data (Carl Worth)

  * Fix broken locking in cairo-ft error path (Chris Wilson)

  * Avoid crash when cleaning up after Render extension (Carl Worth)

  * Avoid crash for zero-sized bitmap glyph (Chris Wilson)

  * Avoid crash with type-1 fonts and ft and atsui enabled (Brian Ewins)

  * Fix many error-handling cases in the Quartz/ATSUI code (Brian Ewins)

  * Eliminate cairo_stroke crash with scaling near zero (Carl Worth)

Other fixes address rendering problems:

  * Fix PDF linear gradients without stops at 0.0 and 1.0 (Adrian Johnson)

  * Fix PDF CFF subsetting to work with Apple Preview (Adrian Johnson)

  * Report proper errors on out-of-memory on win32 (Vladimir Vukicevic)

  * Fix EXTEND_NONE gradients for cairo-quartz (Brian Ewins)

  * Fix odd-number-of-dashes dashing for cairo-quartz (Brian Ewins)

  * Fix erroneous results from cairo_stroke_extents (Carl Worth)

  * Force non-AA text when bitmap strikes are available (Keith Packard)

  * Fix cairo-atsui font metrics (Richard Hult)

And some avoid raising cairo errors for innocent problems:

  * Avoid drawing shutdown for glyph-not-found in font (Behdad Esfahbod)

  * Don't raise an error for creating an empty path (Chris Wilson)

At least one optimization managed to sneak in:

  * Free glyph surfaces after uploading to X server cache (Behdad Esfahbod)

And there are a few very minor fixes, (such as build fixes).
