[art] Optimizing terrain shadows

Hi,
maybe it could be helpful:

IIRC, Morrowind doesn't have directional daylight, so every face of the terrain is facing away from 'the sun', preventing this optimisation. It won't help with regular OpenMW, but if we have an optional overhauled renderer (e.g. something using PBR shaders, IBL and realistic light sources) this could be applied then.

Vanilla Morrowind's shadow implementation, though limited and primitive, did correctly follow the direction of the sun.

Cool article. This could be very relevant when OpenMW begins implementing both dynamic shadows and distant land. And that date might not be too far off.
