Description
The TODO file was mentionning this so I had a look (apparently the implementation in scummvm wasn't done from RE'ing, so there are some differences). The attached patch should implement the decoding of the smush codec 44 as the original interpreters did. Just for the reference, I don't know if it was already known but codec 44 is just codec 21 with a slight difference in the bytes copying (see the patch).
The patch also tries cleanup a bit the NutRenderer class : - by re-using the original smush_decode_codec1 function (is there a need to duplicate it ?) - removing the getCharOffsX and getCharOffsY methods (they were unused...)
I haven't committed this as-is, because : - I haven't tested it that much - This could lead to regressions - I am not a 'SMUSH' expert, so it would be nice if aquadran you could have a look at it, for objections or anything else... - I also got rid of the 'russian' FT version hack, because I'd like to find a proper way of fixing this ; _sev, can you test this patch with your russian version and report if the problem still there ?

i don't see any changes to smush, why i are ask me. But i can comment one thing in nut renderer which was related to me. you don't noticed one thing: "const int srcSize = (_chars[l].width + 2) * _chars[l].height + 1000;" here it's buffer hack "+1000" and you dont'removed it. it's for previous codec bug which write too much sometimes. please check first with proper buffer all fonts if there is no buffer override. I assume you tested codec1 with playing FT intro ?

Ok, thanks _sev and aquadran.
I watched the whole FT intro and didn't noticed any glitches.
Concerning the buffer size hack, I got rid of the +1000 and added some assert() calls. Playing a bit with COMI and FT didn't triggered them.
_sev, in the patch #823031, I saw you also added the +2 to the buffer size, I also got rid of it. Can you try the latest patch with your russian FT version and report here if some assert() calls trigger ?

I decoded all the .nut files from my comi/dig/ft versions (english and/or french), and didn't noticed any problems. Well, except BENBIKE.NUT which was complaining about a missing FRME chunk and BRUSH.NUT which used codec 3, but these are unused.
So, if there's no problem with your Russian FT version, _sev, I plan to commit this.

Works perfectly here with updated patch. So FT Russian-wise it is ok to commit :)
