When there's a relatively small amount of goo in a bulb it's hard to see, and also results in some funky z fighting due to just being a really small amount.

Make it so that even at small values, minimal amounts of goo still have a relatively substantial enough presence in the bulb to avoid tearing and make it easier to see.

Fixed in the next release; minimum of 1% visibility on all goo at any amount keeps things visible.
