Dear Developers,

It was previously noted in the thread "[FFmpeg-devel] libavfilter:
extending overlay filter" that each filter is doing its own
investigation to discover the layout of RBGA style formats, to discover
if the format has alpha, to discover the level of black.

Would it be appropriate to extend AVPixFmtDescriptor to contain a new
struct holding that information, and add that information to
av_pix_fmt_descriptors in pixdesc.c?
