Realistic Waves

Whitecap 2.1.4

Fixed

• No more holes and floating seams in the sea under tall builds. Water with more than six blocks anywhere above it, stacked or spread out (a floating platform, a ship's overhang, a pillar hung over the water), was treated as land: the waves stopped under it, vanilla's lower water showed through as a seam, and a large enough build grew a ring of surf as if it were an island. The sea now runs on under a build over it however tall or thick it is, with the waves kept below its underside. Caves under the ground keep vanilla's water, as before.

Thanks for the detailed report: "seven blocks anywhere above the surface" was exactly the rule.
