nmlgc a89836c18e [Decompilation] [th05] Bombs: Reimu's blue star animation
After ternary expressions straight out of Jigoku in 57be510, we now got
pointer arithmetic straight out of Jigoku… with, unsurprisingly, two
ZUN bugs.

nmlgc a7a053fb52 [Reverse-engineering] [th05] Bombs: Character-specific animation structures
Final structure in TH05's `MAIN.EXE`! And, just like this game's custom
entities, every character uses the same structure fields with vastly
different semantics and high-level types… yup, time for separate
structures again.

nmlgc c5b5dc0201 [Reverse-engineering] General bomb-related globals
Yup, function pointers, frame counters, and general state variables for
all 5 games.

nmlgc 2ef3db3052 [Maintenance] Remove the `operator =` overloads for Subpixels
At least we've now documented their negative effects.

nmlgc 70b4134af4 [Maintenance] [th04/th05] Assemble 16-bit .ASM files case-sensitively
Otherwise, TASM would simply convert all EXTRN declarations in those
files to uppercase. Then, the linker would expect them in uppercase,
forcing both the case-sensitive big 32-bit .ASM files *and* the entire
C land to declare them as uppercase as well.

For functions with __pascal convention which are always uppercased
anyway, this makes no difference. It does matter for regular __cdecl
variables, though, and the C declaration of [score_delta] in e6294c2
already showed that we'd then be forced to use macros if we wanted to
pretend that these names still had lowercase characters.

Doing this for every variable referenced in both C land and 16-bit ASM
land gets annoying quickly. So, no need to force this inconsistency if
we can get rid of it by slightly uglifying ASM land.

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.

nmlgc 8098b62285 [Reverse-engineering] [th05] Aiming to the player
Yes, this only became a dedicated function in TH05, probably due to all
the custom bullet types.

nmlgc d1f3dcd620 [Maintenance] Move all features exclusive to MAIN.EXE to a main/ subdirectory
Adding op/, main/, and end/ directories does nicely cover a great
majority of the "not really further classifiable slices" implied in
d56bd45.
