libpng 1.5.11 doesn't really add much over libpng 1.5.10. However, in order to get 1.5.10 to build, we had to take a fix that didn't actually make it in until 1.5.11. To make life simpler, I would like to update us the rest of the 1.5.11 so that we're in sync with upstream again. Already tested OK on Try. (Yes, I'll fix the commit message before landing)

The part of the patch near the end of png.h looks a little strange: +#ifdef PNG_APNG_SUPPORTED -+PNG_EXPORT(234, png_uint_32, png_get_acTL, (png_structp png_ptr, ++PNG_EXPORT(235, png_uint_32, png_get_acTL, (png_structp png_ptr, + png_infop info_ptr, png_uint_32 *num_frames, png_uint_32 *num_plays)); etc. as though we're splicing in a patch of a previous patch. Shouldn't the "-+" and "++" simply be "-" and "+"? The "diff" view indicates that a lot of line are removed that shouldn't be.

Are you sure you aren't looking at the apng.patch part of the diff?

Ryan, maybe we could include one little fix from bug #759067 too?

That should stay in its own bug. However, apng.patch should probably be updated when it lands. Were you going to request review at some point?
