Changed the moth boss so that the random flight points are now in two pools; splitting the vertical halves of the previous area.  The boss now uses PRNG pools rather than pure random to pick these, and also to pick the general behavior modes (windgust vs. shooting).  Eggs are spawned in larger pools so the max is reached much more quickly.  The windgust speed is considerably more threatening than before.  The attack_area for the boss has been reduced by about 1/3 so the wingtips and such won't hit you - so he's easier to dodge.
