Only seen in Mima's fight, but initialized for all non-final boss
fights. Also with explicit support for all 8 origin edges, not just the
top-right one used in Mima's fight… and an off-by-one error?!

Third longest function in all of PC-98 Touhou, and it's even more of a
copy-pasta than the patterns we've seen earlier. Certainly didn't feel
that long.

The one with two homing snakes, and pellets fired in a semicircle
spread. And yes, Reimu really has a 30×30-pixel hitbox against the
snakes.
Much simpler than its instruction count might suggest. Recalculating
array element addresses over and over is certainly a way to add bloat…
And yes, we're going to see all of this exact same code again in the
four-snake pattern.

Deciding whether to decompile this one or not seemed to be a tough
choice. Should we *really* introduce two more translation units just
for the sake of decompiling another function that's identical to its
TH04 counterpart anyway?
Well, turns out it actually isn't: TH05 does in fact *not* immediately
clip bullets that are spawned on top of the player. Which might sound
like it has a notably different effect on gameplay… except that it
doesn't.
So yeah, good we've decompiled it, and got to show that more clearly.

… (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…

First place to confirm the hitbox of both the 8×8 pellets and the 16×16
sprite bullets!
Well, "hitbox". It's really more of a kill delta of 8×8 pixels between
the center points of a bullet and the player. You can distribute these
pixels to any combination of bullet and player "hitboxes" that make up
8×8. 4×4 around both the player and bullets? 1×1 for bullets, and 8×8
for the player? All equally valid… or perhaps none of them, once you
keep in mind that other entity types might have different kill deltas,
which turns the concept of a "hitbox" into just a confusing abstraction.

At least I *hope* it's an improvement. `point` should be reserved for
actual structures with .x and .y members.
