Snapshot 1.9.10 (2010-06-26)

   The first "quick" snapshot in the run up to the stable release.  The
   last snapshot was picked up by the bleeding edge distributions and so the
   bug reports have to started to roll in.  The most frequent of these are the
   introduction of rendering errors by applications that modify a surface
   without subsequently calling cairo_surface_mark_dirty(). Make sure the
   application developers are aware of increased reliance on strict use of the
   Cairo API before 1.10 is released!

   The usual slew of bugs reported and we would like to thank Zoxc for
   contributing the WGL interface for cairo-gl, and finding more build
   failures on win32.  And it just wouldn't be a 1.9 snapshot unless
   Benjamin Otte improved the error handling within cairo-gl, as well as
   isolating and fixing some more errors in the test suite. The biggest bug of
   the snapshot turned out to be a major sign extension issue that had lain
   hidden for many years and was suddenly exposed by incorrectly rounding
   rectangles when performing non-antialiased rendering.  Also to the relief
   of many we have included the downstream patch to honour the user's LCD
   filtering preferences for subpixel rendering of fonts.  The interface
   remains private for the time being, whilst the proposed public API is
