65d213ec86 Move handling of paletted data to the IFF demuxer. This allows future 
handling of things such as masking/EHB/HAM for this type of data.

79a9672d45 IFF: decode last 8 pixels per line 
The decodeplane8() function processes one byte of input less than
it should.  Also, the for loop has an unusual style with side-effects
in the controlling expression; replaced with a more intuitive while
loop.

fe51b5ce50 Move some branches outside looped code. Should improve the generated asm (and 
thus performance) slightly.

473147bed0 Switch some ints to unsigned (they can only have positive values, this allows 
compiler to optimize some math from mul/div to shr/shl). Also add a cast to
uint32_t when calling decodeplane32(), this silences a compiler warning.
Lastly, in decodeplane8/32(), flatten a double-loop into a single-loop and
calculate the length once before entering the loop instead of during every
iteration (since it doesn't change).

ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

avctx->get_buffer() in case of error, rather than AVERROR_UNKNOWN
