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.

The one where random blue 32×32 bullets rain from near the top of the
playfield, together with aimed spreads from random positions on
Shinki's wings. First white-wing pattern.

The one where Shinki fires bullets in a ring, with each new ring fired
at an increasing or decreasing angle, for a curved effect. The first
pattern you see in the fight.
At least the pattern functions are short and sweet for the most part.
