8c151364df Add special handling for CullVisitor to QuadTreeWorld. 
- Cull only against bounding box, not bounding sphere, as this appears to perform better.
- Also traverse into non visible nodes to compute their LOD, this is to avoid nodes having to be loaded in when the player turns the view around, and will avoid unnecessary refs/unrefs of rendering data in the View. This should probably be turned off at some point for static cameras, such as the local maps.

e27437f8ed New terrain renderer - improvements: 
- 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
