This adds handling of spherical video metadata: retrieving it from demux_lavf and demux_mkv, passing it through filters, and adjusting it with vf_format. This does not include support for rendering this type of video. We don't expect we need/want to support the other projection types like cube maps, so we don't include that for now. They can be added later as needed. Also raise the maximum sizes of stringified image params, since they can get really long.
