Release 1.12.6 (2012-10-22 Chris Wilson <chris at chris-wilson.co.uk>)
Thanks to everyone who download cairo-1.12.4 and gave us their feedback.
It truly was invaluable and has helped us to fix many portability issues
that crept in with some of the new features. This release aims to fix
those stability issues and run on a wider range of systems.

Bug fixes

  Fix the recording surface to actually snapshot the source and so fix
  PDF drawing.

  Calling XSendEvent with an XShmCompletionEvent is incompatabile with
  older Xorg servers.

  Reorder CloseDisplay chain so that XShm is not reinstantiated after
  shutdown, causing a potential crash if the Display was immediately
  recreated using the same memory address.

  Make sure that the Xserver has attached to the SHM segment before
  deleting it from the global namespace on systems that do not support
  deferred deletion.

  Type1 subsetting support for PDF (and PS) was once again improved to
  work with a larger number of PDF readers.

  GLESv2 build fixes and improved support for embedded GPUs.

  Tweak the invisible pen detection for applications that are currently
  using too large values for geometric tolerance.

  A build fix for older freetype libraries.

Cairo - Multi-platform 2D graphics library

What is cairo
Cairo is a 2D graphics library with support for multiple output
devices. Currently supported output targets include the X Window
System (via both Xlib and XCB), quartz, win32, and image buffers,
as well as PDF, PostScript, and SVG file output. Experimental backends
include OpenGL, 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,

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
