Here testing that layer is a CALayer is a requirement. ie: -[NSObject
isKindOfClass:].

That would also allow us to set a higher capability on the vout. This
let libvlc clients select this vout, just by passing a CALayer instead
of a NSView. Documenting this behavior in media_player_set_nsobject
would be a bonus :)
