| Description: |
| Updated to 1.6.35, stripped all unneeded files. |
| |
| - Use custom configuration file pnglibconf.h, which turns off all features that |
| are not in use. |
| - Use custom prefix file pngprefix.h, which avoids namespace conflicts with |
| pdfium's copy of libpng. |
| - Configures custom png chunk user limits (crbug.com/117369) in pnglibconf.h. |
| - Applies the patch in patches/0000-plte.patch for ARM NEON optimizations (this |
| change has been accepted to upstream [1] but not yet released). |
| - Applies the patch in patches/0001-chunkerror.patch (modify |
| png_check_chunk_length to call png_benign_error instead of png_chunk_error -- |
| see crbug.com/827754). |
| - Keeps the fuzz target in contrib/oss-fuzz/ for running on clusterfuzz. |
| - Applies the patch in patches/0002-fuzzeroom.patch to prevent clusterfuzz |
| running into OOM errors. |
