[Decompilation] [th05] Committing the score delta Completes P0029, funded by zorg.

[Decompilation] [th04/th05] Handle subpixels at the C++ type level I've had the idea to hide this implementation detail and improve code readability for some time now, but it obviously must still all inline, to be indistinguishable from a direct assignment of the correct value… … which, amazingly, it does! Even the static_cast from float to int. The latter allows us to exclusively implement this for float, since we do have to express the occasional value smaller than 16. Who needs macros anyway. Yay, C++ in TH04 and TH05 after all! Part of P0030, funded by zorg.

#include "th04/shared.hpp"
[Decompilation] [th05] Stage setup "Yeah, let's do this real quick, how can this possibly be hard, it's just MOVs and a few function calls"… …except that these MOVs access quite a lot of data, which we now all have to declare in the C world, hooray. Once it came to midbosses and bosses, I just turned them into C structs after all. Despite what I said in 260edd8… after all, the ASM world doesn't care about the representation in the C world, so they don't necessarily have to be the same. Since these structs can't contain everything related to midbosses and bosses (really, why did all those variables have to be spread out like this, ZUN?), it also made for a nice occasion to continue the "stuff" naming scheme, describing "an obviously incomplete collection of variables related to a thing", first seen in 160d4eb. Also, PROCDESC apparently is the only syntactically correct option to declare an extern near proc? Also, that `boss_phase_timed_out` variable only needs to be here already because TCC enforces word alignment for the .data segment… yeah, it's technically not related to this commit, but why waste time working around it if we can just include that one variable. Completes P0030, funded by zorg.

[Decompilation] [th05] Stage-related .BB file loading boilerplate Yay for alignment, allowing us once again to only move unrelated variable declarations over to C… Part of P0031, funded by zorg.

[Reverse-engineering] [th05] Player shot cycle bitflags A TH05 innovation that actually makes the game code easier to read?! Although it was quite hard to actually reverse-engineer it, with the confusing flag ordering pointing to some deeper meaning behind the flags, which really doesn't exist. Completes P0036, funded by zorg.
