There are two issues - one is that cairo-png is treating every warning
as fatal.  The other is that libpng 1.6 has stronger function call
ordering enforced, so cairo-png's loader causes a warning.  Which then
gets turned into the "out of memory" error.

I'm working with Chris Wilson now to try and sort this in cairo git,
so we can backport stuff.
