Snapshot 1.11.2 (2011-01-23)
===========================
In this first snapshot along the way to cairo-1.12.0, we are very excited
to announce the introduction of Bezier surface gradients, known as type
6/7 gradients in PS/PDF parlance. This is the culmination of much work by
the dynamic duo: Adrian Johnson and Andrea Canciani. Thanks guys!
Also, I want to warmly welcome Uli Schlachter who recently joined the
Cairo community on a mission. That mission is to make cairo-xcb a
supported backend for 1.12. And for this snapshot he has made great
strides in fixing all the bugs I had left behind. Thanks Uli!
And we have also seen a new contributor, Alexandros Frantzis, who has
begun bringing up cairo-gl for GLESv2 devices. Thanks Alex!
And lastly, I must also thank Adrian and Andrea for the vast numbers of
bugs that they have tackled between them, fixing all those little corner
cases that lie hidden until too late.

API additions:
The ability to construct piece-wise Bezier surface gradients:
cairo_pattern_create_mesh
constructs a pattern of type CAIRO_PATTERN_TYPE_MESH using
cairo_pattern_mesh_begin_patch
cairo_pattern_mesh_end_patch
cairo_pattern_mesh_curve_to
cairo_pattern_mesh_line_to
cairo_pattern_mesh_move_to

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.
