I agree that it probably isn't useful, but we need to be careful with
the condition to not exclude *useful* formats, like r8g8b8 on depth 32,
or r5g5b5 on depth 16. Of course, the real fear is deleting a format
that an existing app is relying on...

I think that's because you don't have a depth 15 visual.
