Release 1.12.16 (2013-08-21 Chris Wilson <chris@chris-wilson.co.uk>)
===================================================================
Thanks to everybody who reported a bug and helped us develop a fix,
we have amassed quite a few bug fixes. There are still more outstanding
bugs that seek attention and a little bit of TLC, but this release has
been delayed long enough...

Bug fixes
---------

  Set the correct orientation for simple boxes with a negative scale
  factor.

  Fix the creation of the shading dictionary in PDF.

  Fix a crash in PDF when incorporating an image with CAIRO_EXTEND_PAD.
  https://bugs.freedesktop.org/show_bug.cgi?id=61451

  Avoid upscaling bitmap fonts if possible.

  Fix an assertion failure within the mempool allocator for shared memory.

  Fix allocation size for CFF subsets.

  Export cairo_matrix_t for GObject bindings.

  Fix a double free in the Quartz backend.
  https://bugs.freedesktop.org/show_bug.cgi?id=62885

  Fix unbounded operations with a clip mask through the span compositor

  Add missing checks before rendering to a finished surface - so we return
  an error rather than hit an assert.
  https://bugs.freedesktop.org/show_bug.cgi?id=68014

  Prevent an assertion failure when creating similar GL surfaces larger
  than supported by hardware.

  Prevent a double free of a similar image under Windows.
