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.

What is cairo
=============
Cairo is a 2D graphics library with support for multiple output
devices. Currently supported output targets include the X Window
System, quartz, win32, and image buffers, as well as PDF, PostScript,
and SVG file output. Experimental backends include OpenGL, XCB, BeOS,
OS/2, and DirectFB.
Cairo is designed to produce consistent output on all output media
while taking advantage of display hardware acceleration when available
(for example, through the X Render Extension).
The cairo API provides operations similar to the drawing operators of
PostScript and PDF. Operations in cairo include stroking and filling
cubic Bézier splines, transforming and compositing translucent images,
and antialiased text rendering. All drawing operations can be
transformed by any affine transformation (scale, rotation, shear,
etc.).
Cairo has been designed to let you draw anything you want in a modern
2D graphical user interface. At the same time, the cairo API has been
designed to be as fun and easy to learn as possible. If you're not
having fun while programming with cairo, then we have failed
somewhere---let us know and we'll try to fix it next time around.
Cairo is free software and is available to be redistributed and/or
modified under the terms of either the GNU Lesser General Public
License (LGPL) version 2.1 or the Mozilla Public License (MPL) version
1.1.
