In the interest of progress, please allow me to sidestep this question
(and the opt.h question) as follows:
1) For now, I will include avcodec.h in avfilter.h; if the color
rendering enums are moved out, only this line would need to be changed.
2) I will encode color_primaries, etc. into the `args' string currently
being passed to the vsrc_buffer init routine, which will now expect 10
colon-separated arguments rather than 5. This affects only the `buffer'
I think there is agreement to place the 5 enums into the AVFilterLink
If everyone agrees with this I can proceed.
