nmlgc 1244bd74e7 [Maintenance] Prefer the -zC and -zP options over `#pragma codeseg`
Might look uglier, but has the advantage of not generating an empty
segment with the default name… *and* the default padding, which will
really come in handy with the following breakthrough.

nmlgc eb89330f64 [Build] [th01] Move the -Z and -3 options onto the command line
Deactivating them is the exception, not the norm.

nmlgc 37d191d903 [Decompilation] [th01] Player invincibility sprite rendering
So ZUN *did* want to clip those at the left and right edges of VRAM,
but accidentally tested the Y instead of the X coordinate 🎺

nmlgc 51de73bcc9 [Decompilation] [th01] Orb physics
"Physics". Not only did ZUN restrict the X velocity to the 5 discrete
states of -8, -4, 0, 4, and 8 (because hey, unaligned blitting is slow
anyway?), but gravity is also only applied every 5 frames.

We're still missing quite a bit of usage code, but these are the core
functions. One of which turned out to be undecompilable, due to… a
rigorously defined instruction order when performing arithmetic between
`double`s and `float`s?! Still, spelling out all this stuff in ASM
seems much better than somehow splitting the data segment, just so that
we can immediately use literals there.
