[XviD-devel] "Autoselecting" IDCT for SimpleIDCT encodes

sysKin has a hack ready for xvid dshow with which we can change the
decoding IDCT from/to walken/simple. Since there are a few bitstreams
out there with the bitstream number 009 (I think) we were thinking about
adding an automatic pre-selection in bitstream.c (switch to simple if
bitstream number is 009) - if that selection is wrong, the user still
can select the idct from dshow.
Unfortunately this is a hack which only works because we statically link
xvid core into dshow. It would be more graceful if we'd extend the API
"(@sysKin): a flag in "frame" I guess - if flag is on && bitstream
version is 009 -> switch"
Any objections? :)
