There's nothing anywhere ensuring the presence of the swizzle.  I
completely agree that trashing the components value is a bad idea, but
you should have SWIZZLE_X as a default value for the components array.

Amusingly enough, it's already the case (SWIZZLE_X==0), so making it
explicit would be perfect.
