I don't like the names. If you add something to the vo system it
should be generic, not dvdnav specific.
I hope the plan is spu rendering to replace the current osd one.

On second look all the formats already have fourcc for their
non-subtitle part and in most cases they would be the same as the
primary colorspace.

There is one big difference however, the fmt should be able to support
alpha channel. It would be best if swscale could be used for
conversion.
simplest solution is to have normal image in the give fmt and separate
alpha-channel image.
(well rgb32 already have space for alpha channel but....)
