I said:

It is to be a filter that has constraints similar to vf_crop.

But also, ff_all_formats() can be implemented in terms of this function,
which makes it more efficient (there was an old thread about this).

Also, I just checked: all these filters do a similar thing in their
query_formats() function, which means this should have been done years
ago. I don't intend to change them all, anybody can do it.

vf_boxblur.c
vf_copy.c
vf_detelecine.c
vf_fieldhint.c
vf_fieldorder.c
vf_hflip.c
vf_hwdownload.c
vf_il.c
vf_mix.c
vf_noise.c
vf_stack.c
vf_swaprect.c
vf_swapuv.c
vf_telecine.c
vf_transpose.c
vf_weave.c
