Fill ocean water across entire tile to fix missing harbor water

Browse source 
Coastal areas like Booty Bay had gaps in ocean water where MH2O
data didn't cover harbor chunks (only 34/256 chunks had ocean
entries). For sea-level ocean surfaces (type=2, height~0), the
mask is now initialized to fully visible instead of empty, letting
depth testing against terrain handle land occlusion naturally.
