Yeah, separate might be nice, but I'm fine with this. I think I want to
see if I can rethink some of the format check stuff all over anyway.
That might want the separate the functions or it might not. I don't
think I'll know until I try and see how it would all turn out.
In the meantime we can proceed with this.
But plese drop the plane type BUG_ON()s. We've generally decided to not
do BUGs anymore, and we don't have such things in any other plane vfunc
either. Oh, and it looks like you have some tabs vs. spaces mess in that
sprite funciton.
