There was a massive performance issue when I attempted to debug the lighting system. It appears that the lighting is recalculated each tick or frame. It would be preferable if this is only recalculated when necessary, i.e. "dirty" state.
Acceptance Criteria
[ ] Lighting is only recalculated when the viewshed (or map?) has been marked dirty.
[ ] Existing effects and other code has been audited to ensure that this does not cause issues with lighting effects.
