nmlgc b61e612fdf [Maintenance] #include each header's dependencies within the header itself
OK, this is the big one. We still keep using `#include` guards only
where we absolutely need to, but with each header now being valid in
isolation, this can now actually help *minimize* the length of each
translation unit's `#include` list. Turns out that after removing all
the duplicates, we only *actually* need to guard 29 headers across all
5 games.

nmlgc 540174828b [Maintenance] [th05] Bullets: Explicitly use the blue and red ball patnums
PAT_BULLET16_N_BLUE and PAT_BULLET16_N_RED are just meant to be generic
color range indicators with no semantic meaning.

nmlgc 71cb7b5e93 [Decompilation] [th05] Shinki: Main function
3rd PC-98 Touhou boss completely decompiled, 28 to go… and the code
quality is taking a nosedive again, especially with that unnecessary
"relative phase" variable that collides with the laser activation flag
in the Devil pattern.
(The nearfunc_t_near workarounds are our fault, though!)

nmlgc 8b79dd5371 [Decompilation] [th05] Shinki: Pattern 8/11
The one where Shinki's white wings turn purple, and fire 16 purple
32×32 bullets after the color change.

For some reason, OMAKE.TXT says that these wings are black?!?

nmlgc 3b21a75cab [Decompilation] [th05] Shinki: Pattern 5/11

of state set by an earlier boss, which technically affects gameplay!

Featuring something that looks like part of an unused pattern, but was
actually just copy-pasted from Yumeko. Some evidence for Shinki having
been coded after Yumeko, at least.

… (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 9739f69729 [Maintenance] Add a 1bpp rectangle template, for custom per-row types
This gets rid of a couple of per-entity sprite bitplane types, makes
sprite declarations easier to read by putting width and height next to
each other… and points out a number of array dimension mistakes -.-
Even in places where we can't use it.

nmlgc ec5b75daab [Maintenance] [th05] Yumeko's blades are actually swords, as stated in OMAKE.TXT
*Technically* also a uth05win inaccuracy. That codebase went with
"KnifeBullet", which seemed right, so I just ran with it without
researching it further… My bad.

nmlgc 3c27fbc3bd [Decompilation] [th05] Player character selection menu

that's actually identical in both games is the picture darkening loop.

pointer arithmetic straight out of Jigoku… with, unsurprisingly, two
ZUN bugs.

nmlgc 2c7d86bc5b [Decompilation] [th05] Mai & Yuki: Smooth random movement
Wow, so the boss_stuff_t structure did exist in the original code after
all. This is the only function in all of TH04 and TH05 that confirms
it – in dea40ad, it just seemed like something I made up, out of
convenience.

A future sprite converter (documented in #8) could then convert these
to C or ASM arrays.

(Except for the piano sprites for TH05's Music Room, which are stored
and used in such a compressed way that it defeats the purpose of
storing them as bitmaps.

nmlgc 8a9cb158b6 [Reverse-engineering] [th05] Custom entity 6: Shinki's 32×32 balls
Which need to be separate from Mai's and Yuki's 32×32 balls because…
they have a delay cloud, whose radius absolutely has to be stored
redundantly, rather then deriving it from the [age]? Same for the decay
frame count. And the _update() function was copy-pasted from the knife
one…
