I don't think there is something particularly special or wrong in respect to
the light management in this game's code, apart from the fact it is Directx 4
game and the lights were attached to viewports in Directx X < 7. I came across
some problems managing that in Wine while testing the other bug related to
lighting in some other ddraw4 games. Now they are hopefully fixed and it might
fix a number of ddraw2-4 titles. Just to note, lighting in ddraw1 still does
not fully work for completely different reasons.
