| Description: |
| Updated to 1.6.22, stripped all unneeded files. |
| |
| - Turn on SSE optimizations for Intel platforms by running: |
| "patch -i contrib/intel/intel_sse.patch -p1" |
| - 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. |
