-Subject: [PATCH] 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.
