It would be better if all colorspace and pixel convert code would be
in the same lib.
Especially for automatic convertion
swscale since last GSoC applies the individual scale and convert steps
through a more generic system, and should be possible to add this
in there. Quite possibly that would be more work and require some more
changes and cleanup in swscale.
swscale also supports spliting convertions into multiple swscalers,
so you could easily have a swscale that uses this as a special
converter connected to a 2nd swscale that does all the rest.
Also iam sure pedro would help and awnser any questions as his time
permits about the improvments added in last GSoC.
anyway thats not a objection, i just think this isnt the best way
to implement this
