a failing png file

FastStone Image Viewer mostly works under Wine, but it fails to open some PNG
images. When this happens, the app just exits instead of showing the image.

Looking at the logs, Wine prints this message every time the failure occurs:

`fixme:wincodecs:copypixels_to_24bppBGR Unimplemented conversion path!`

However, the same PNG files open fine on native Windows. Other PNGs work under
Wine, so I think this is something format-specific (likely bit depth / color
format).
