Load .IFF files saved by Deluxe Paint ST in "vert word" compression

[miniupnp]

The Atari ST version of Deluxe Paint supports 3 compressions modes :
0 = NONE
1 = BYTE RUN
2 = VERT WORD

the BYTE RUN compression is the same as Deluxe Paint Amiga.
VERT WORD is specific to ST version

I have implemented support for loading such files.
see attached patche
and example IFF files supplied with the ST version of Deluxe Paint

my patch is based on r2169 of the SVN sources

Applied in r2168. (there is no r2169 yet?)
Thanks!

I tested all the IFF files from our test suite and most are still not loading or showing some garbage data, but there is some progress. I will add your two test files there as well.

I had a look at the .IFF from the test suite. Many are truncated (copy error from old floppy disk ? :)

But I've found a bug with monochrome images which have no palette. I think I should rework the IFF loader to debug it.
