download feh 3.8
- Add flip and rotate options to the menu
- Improve unloadable image detection time (e.g. for large video files) by
checking a file's header before passing it to Imlib2. For rarely used
image formats, there is a very small chance that an image which could be
loaded by feh 3.5 is reported as unloadable by feh 3.6 due to this
FEH_SKIP_MAGIC=1to bypass the header check in this case. See https://phab.enlightenment.org/T8739 and https://github.com/derf/feh/issues/505 for details.
