Changes compared to old (Ogre) water:
- Uses depth-texture readback to handle the underwater fog in the water shader, instead of handling it in the object shader
- Different clipping mechanism (glClipPlane instead of a skewed viewing frustum)
- Fixed bug where the reflection camera would look strange when the viewer was very close to the water surface
- Toned down light scattering, made the waterColor a bit darker at night
- Fixed flipped water normals and strange resulting logic in the shader
Still to do: see comments...
conversion from 'const float' to 'int', possible loss of data

- Consistent triangle alignment, fixes a noticable crack near the census and excise office. Note that alignment is still not the same as vanilla. Vanilla uses a weird diagonal pattern. I hope there aren't more trouble spots that will force us to replicate vanilla, but at least we can do that now.
- Fixes several blending issues and cell border seams
- Fix map render to use the terrain bounding box instead of an arbitrary height
- Different LODs are now properly connected instead of using skirts
- Support self shadowing
- Normals and colors are stored in the vertices instead of a texture, this enables per-vertex lighting which should improve performance, fix compatibility issues due to the PS getting too large and mimic vanilla better
- Support a fixed function fallback (though the splatting shader usually performs better)
- Designed for distant land support - test: https://www.youtube.com/watch?v=2wnd9EuPJIY - we can't really enable this yet due to depth precision issues when using a large view distance
