| FAQ: |
| Q: Why does this directory exist? |
| A: libpng is pulled in through DEPS, but in order to build it using ninja, we |
| need to create pnglibconf.h and pngprefix.h. We originally tried creating |
| the file as an action in https://codereview.chromium.org/930283002/, but this |
| apparently led to a race condition on Windows, where some builds failed to |
| create the file in time for other files to include it. By checking these |
| files directly into Skia, we eliminate the race condition. |
