+commit 95f6f7a174ca096a3d3dbe84ff220d166d1e2baa
+Author: Uli Schlachter <psychon@×××.in>
+Date:   Fri Oct 22 11:54:57 2010 +0200
+
+    Make both versions of _cairo_lround consistent again
+    
+    Commit c0008242b0f made cairo use libm's lround instead of its own _cairo_lround
+    by default. However, since commit ce58f874 from 2006, _cairo_lround does
+    arithmetic rounding instead of away-from-zero rounding (before said commit, it
+    was using baker's rounding).
+    
+    So to make the rounding of _cairo_lround be independent from
+    DISABLE_SOME_FLOATING_POINT, we have to use another function. Turns out that
+    _cairo_round already does the same thing that _cairo_lround does. Their only
+    difference is the return type.

+Subject: xlib/shm: Force synchronisation for scratch SHM image buffers
+
+The scratch image buffers are used for uploads to the xserver and so we
+must be careful not to overwrite active SHM segments. Unfortunately we
+told the core SHM allocator that we would sync before using the images,
+which was a lie.

+Subject: png: Avoid marking the surface as in error after a png warning
+
+It turns out that libpng will continue to load an image after throwing a
+warning, and that libpng16 now throws warnings for images that libpng15
+and earlier loaded without error. As we were happily loading those
+images into cairo surfaces before, we are therefore being overzealous
+in throwing an error now - so just squelch the warning.
