Alright Michael, I'm not entirely sure of what I'm doing regarding the 
FFALIGN(avctx->width, 32), but at least the two odd-width (113 and 129 
pixels) 1 bpp files that failed to render correctly with the last patch 
now seem to be OK. Please give it a try. Original description follows:

Match the use of AV_PIX_FMT_PAL8 for 1-bit QuickTime Animation in 
lavc/qtrle. To reiterate, 1-bit video is not necessary black & white in 
QuickTime, merely bi-level. The two colors can be any color. The 
palette, either included in the sample description, or the default 
Macintosh palette (black & white for 1-bit video) will be set in 
lavf/qtpalette. See the QuickTime File Format Specification for details.

Mats
