nmlgc 4d24ca53bd [Decompilation] [th04/th05] Bullets: Update function
… (24 + (difficulty * 8) + rank) in TH04, and (42 + (difficulty * 8))
in TH05. Also, TH05 only doesn't have TH04's bullet zap animation
because ZUN didn't consistently use constants…

nmlgc 75c4f2d3cc [Reverse-engineering] [th04/th05] Bullets: Distinguish clear and zap mechanics
And actually document them correctly.

Clear: Custom duration, awards constant points per bullet during the
       entire duration, plays a decay animation
  Zap: Fixed duration, awards a semi-exponential bonus for all bullets
       alive on the first frame, plays a, um, "zapping" animation… in
       TH04, because it's bugged in TH05 :zunpet:

nmlgc da6b856dc5 [Reverse-engineering] [th04/th05] Stage enemy structure
Last one of the shared entity types! The TH05 version of the .STD enemy
VM would now be ready for decompilation in one single future push.

nmlgc ba66fcc801 [Reverse-engineering] [th04/th05] Currently alive player shots
Copying out the shot position might have actually been a decent
optimization for hit detection, to avoid the indirection if the shot
is not colliding with anything.
