+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.
