The new lighting which was introduced in beta 1.8 is even today "broken"
and kind of "cuts" off and smooth lighting even appears in completely dark
aeras. Areas with the light level 0 had no smooth lighting in the old lighting
engine, which now could be a solution to the problem we are having since
the new lighting engine was added. I've included pictures of the current
lighting and a few pictures from version beta 1.7.3 demonstrating that
there was no smooth lighting at light level 0 and no transitioning problems.
