| Description: png compression/decompression library |
| Local Modifications: |
| (1) Created pnglibconf.h from pnglibconf.h.prebuilt. This |
| is mostly a rename, with Skia-specific settings at the end. |
| The only difference is for pngprefix.h. |
| (2) Included Intel optimizations by running: |
| "patch -i contrib/intel/intel_sse.patch -p1" |
| (3) Removed files unused by Skia |
| (4) Fixed an undefined behavior bug (skbug.com/5390) |
| (5) Add pngprefix.h, so multiple versions of libpng can |
| coexist. |
