If var->xoffset has the low order bits set (sub-word pixel offset)
par->hw.falcon.xoffset takes care of that, and xoffset takes care of the rest.
Since the partial word offset shifts the beginnig of the scan line into the
first word, the offset to the next scan line (par->hw.falcon.line_offset) has to
be shortened.
Sounds reasonable. But the shortening part doesn't work on ARAnyM, nor do
small panning increments. So it really smells like an ARAnyM bug.
Petr said as much if I understand him right. No need to fix ARAnyM though, we
just need to keep that in mind.
ARAnyM's VIDEL emulation has already been fixed by Patrice (yesterday
night, in CVS).
I can confirm that (for depths 2, 4, and 8). However, it's not flicker-free.
Dunno if that's an atafb or ARAnyM issue.
