Element.glow ignores {opacity: 0}

[spookylukey]

Element.glow({opacity: 0}) (which is useful in the context of later animating the glow) behaves the same as Element.glow({}). It's easy to see why:

opacity: glow.opacity || .5,

It should instead be checking for something like glow.opacity == null

Actually I think it should be:

opacity: glow.opacity === undefined ? 0.5 : glow.opacity

Another alternative: opacity: glow.opacity == null? .5 : glow.opacity;
It catches both null & undefined in the same check! :P
