New ocean heightmap rendering isn't clipped by land if simplify lines is used

[christopher0936]

Picture of issue

Steps to reproduce Set up a style that utilizes rendered water heightmaps and set line simplification to a number greater than 0

Expected behavior Water heightmap simplified lines should be clipped or "cut off" by the presence of land, and the simplified line should resume on the other side of the intruding bit of land.

That's how it works, I cannot do anything with that without a major rework.
