Support for METABLOCK_DATA_PICTURE in xiphcomments?

[Martin Brodbeck]

Hello,

I recently learned that the recommended way of adding cover art to ogg files 
(vorbis comments) is to use METABLOCK_DATA_PICTURE instead of the unofficial 
COVERART field, just likeit is done in FLAC files (see [1]).

By the way, if you encode an opus file from flac (with a flac picture) using 
opusenc (from opus-tools >= 0.1.7), it uses METABLOCK_DATA_PICTURE.

AFAIK, taglib supports FLAC pictures very well. Since the recommended 
xiphcomment way is exactly the same as in FLAC, it would be nice to have the 
same support here, I think.

Are there any plans to add this? 

Thanks,
Martin
