Detailed Description
This model is a dynamic light.
It handles a PointLight, where Pos is the worldPos updated by CScene at each render(). CPointLightModel are linked to the LightModelRoot in the LightTrav. It can handles SpotLight too, see PointLight.
Hrc: Lights herit CTransform so they can be put in hierarchy, even sticked to a skeleton. They can be hide, moved etc... (default CTransform). Clip: Lights are always in frustum, not renderable (default CTransform). Light: lightModels are not lightables (ie they can't be lighted). (default CTransform). the observer is specialised.
PERFORMANCE WARNING: big lights (disabled attenuation and big attenuationEnd) slow down performances. (by experience, with a factor of 2).

setup the deltaPosToSkeletonWhenOutOfFrustum When a light is sticked to a skeleton, and if this skeleton is clipped, then the position of the light can't be computed correctly without animating the skeleton.
To allow good position of the light, and to avoid recomputing the skeleton even if it is clipped, the light position is set to skeletonMatrix * this "deltaPosToSkeletonWhenOutOfFrustum".
Default is (0, 0, 1.5). You may change this according to the approximate size of the skeleton (dwarf or giant), and you must take into account any mount (horse etc...). eg for a man on a elephant, a good value would be (0,0,5) :)

Same problem as _DeltaPosToSkeletonWhenOutOfFrustum, but this one is computed at each Visible frame.
And we interpolate between actual direction and backuped direction when the spot become visible (5 frames, hardcoded)

The pointLight setup (color/attenuation).
Do not use PointLight.Pos to setup the position. Use the CTransform interface to set the position. To enable SpotLight, use PointLight.setType(), and use PointLight.setSpotAngle() but don't use PointLight.setSpotDirection to setup the direction. The direction of the spotLight is driven by the J vector of the Transform WorldMatrix.
