Patch fixing the problem, needs png-1.5.1.

png-1.5 hides structure members from public view. For this reason, some code doesn't compile any more.

The attached patch, mostly from John Bowler <jbowler at acm.org> fixes the problem.
Some discussion on the solution:

Since webkit-gtk used internal data that wasn't available via the public interface, the interface has been extended. The patch already makes use of it, which requires png-1.5.1 though. I'm not sure how you want to handle that.
