When WCS headers with TPV distortions like below are used, Gnuastro won't convert pixel to WCS coordinates (and vice-versa) properly! Producing incorrect results.

Corresponding source code
This bug has been fixed and merged into Gnuastro as Commit d3deff2954.
The same header now looks like this. I added a comment for the users who may be use to having CDELT in Gnuastro's outputs, but also for ourselves in a few years when WCSLIB 7.4 becomes very widely used, we can consider if we want to keep this feature or not.
