lawnjelly b09bc22b74 Tighter light culling - fix directional lights colinear case 
Exactly the same fix as done already for non-directional lights.

lawnjelly 46a04d160e Tighter shadow culling - fix light colinear to frustum edge 
In rare situations if a light is placed near colinear to a frustum edge, the extra culling plane derived can have an inaccurate normal due to floating point error.
This PR detects colinear triangles, and prevents adding a culling plane in this situation.

lawnjelly 8ca631a466 Shadow volume culling and tighter shadow caster culling 
Existing shadow caster culling using the BVH takes no account of the camera. This PR adds the highly encapsulated class VisualServerLightCuller which can cut down the casters in the shadow volume to only those which can cast shadows on the camera frustum.

This is used to:
* More accurately defer dirty updates to shadows when the shadow volume does not intersect the camera frustum.
* Tighter cull shadow casters to the view frustum.

Lights dirty state is now automatically managed:
* Continuous (tighter caster culling)
* Static (all casters are rendered)
