All of the builds are now passing, including the Cygwin builds:

The Cygwin problem wasn’t reproducible on a bare metal system.  It looks like 
we were hitting some odd behaviour relating to Docker storage layers, where 
seek and fread were behaving incorrectly resulting in corrupted TIFF files.  
I’ll file a bug report about this, but in the interim I’ve reverted the Cygwin 
builds to run on a bare metal runner while the MSVC and MinGW runners are 
working fine in a container.

Kind regards,
Roger
