According to flickr, the original resolution is actually 2560x1920. The
2048x1536 is just an alternative downscaled download format offered by
flickr.

If the 2560x1920 PNG download were a fake, it would be a surprisingly
good one, including POV-Ray-typical PNG header features.

We can even learn that the file was rendered on 2016-01-07 around 10:24
UTC using an unofficial 64-bit build of POV-Ray 3.7.1-alpha.8141620 for
Windows, compiled with MS Visual Studio 2010.

The 2048x1536 JPEG version, on the other hand, shows clear signs of NOT
having being created with POV-Ray, but rather having been generated from
the 2560x1920 PNG original.
