+ Release 1.12.4 (2012-10-05 Chris Wilson <chris at chris-wilson.co.uk>)
+ ===================================================================
+ More bugs, and more importantly, more fixes. On the cairo-gl side, we
+ have refinements to the MSAA compositor which enables hardware
+ acceleration of comparitively low-quality antialiasing - which is useful
+ in animations and on very high density screens. For cairo-xlib, we have
+ finally enabled SHM transport for image transfers to and from the X
+ server. A long standing required feature, SHM transport offers a notable
+ reduction in rendering latency by reducing the number of copies
+ required to upload image data - given hardware and driver support,
+ cairo-xlib can now perform zero copy uploads onto the GPU. And as usual
+ Adrian Johnson has been very busy fixing many different corner cases in
+ cairo-pdf, impoving opacity groups and font subsetting. Last, but not
+ least, for cairo-image S=F8ren Sandmann Pedersen added support for
+ rendering glyphs to pixman and using that from within cairo. The new
+ glyph rendering facility reduces the overhead for setting up the
+ compositing operation, improving glyph thoughput for the image backend
+ by a factor of about 4. And before he did so, he also fixed up a few
+ bugs in the existing glyph rendering code. So many thanks to Andrea
+ Canciani, Adrian Johnson, Chuanbo Weng, Dongyeon Kim, Henry Song, Martin
+ Robinson, S=F8ren Sandmann Pedersen and Uli Schlachter for their
+ contributions, finding and fixing bugs.
