maybe add a comment that this is used for the fadeout animation?

Done.

Use CGFloat instead?

[groby-ooo-7-16, 2013/09/04 22:19:01]

Reluctant, because '0' is a special case - and equality on floats makes me feel
weird :)

I think it's still a good idea to make this a CGFloat. We check against 0 all
the time.

[groby-ooo-7-16, 2013/09/05 00:44:20]

Done, then.
