git checkout -b build 1.8.6

The cairo community is pleased to announce the 1.8.6 release of the
cairo graphics library. This is the third update to cairo's stable
1.8 series and contains a small number of bug fixes (in particular a
few fixes for failures of cairo 1.8.4 on Quartz and PDF, and build fixes
for a couple of backends). This is being released just under a month
after cairo 1.8.4.

We recommend that everyone using cairo upgrade to 1.8.6.

Build fixes
-----------
Fix build of DirectFB backend with debugging enabled:

   Bug in _cairo_directfb_surface_release_source_image function
   http://bugs.freedesktop.org/show_bug.cgi?id=18322

Fix build on OS/2.

Bug fixes
---------
Workaround a mis-compilation of cairo_matrix_invert() that generated
invalid matrices and triggered assertion failures later. The issue was
reported by Peter Hercek.

Invalid computation of the modulus:

   https://bugzilla.mozilla.org/show_bug.cgi?id=466258

Invalid referencing of patterns in the Quartz backend:

   Failed assertion `CAIRO_REFERENCE_COUNT_HAS_REFERENCE
   (&pattern->ref_count)' when using cairo quartz backend
   http://bugs.freedesktop.org/show_bug.cgi?id=18632

Invalid references to glyphs after early culling, causing segmentation
faults in the PDF backend:

http://lists.cairographics.org/archives/cairo/2008-December/015976.html

Check for XRender in the XCB backend, or else we may attempt an invalid
memory access:

    XCB backend fails with missing render.
