| Imager 0.74
- read_multi() didn't handle a missing file format library correctly, aborting on failing to call i_readgif_multi_wiol() or i_readtiff_multi_wiol().
- fix spelling errors patched by Debian
- add an (unshipped) author test to spellcheck Imager's POD.
- update the TIFF file format documentation
- lib/Imager/IO.pod was written almost 4 years ago but never shipped.
