I have no idea how that one got past me ;-)

I've removed INFO_VIDEO from video_info, because it duplicates
get_depth_bits(), and I doubt anyone has used it. Sorry to toss a monkey wrench

I've added a get_info() method to surface objects. This returns a bitmask

I'll do a release shortly, so whatever you're writing will work out of the box.
If you find you need any other features, let me know.
