On the surface, TH05 uses one single 26-byte structure for
• the Stage 2 starfield,
• Alice's puppets,
• curve bullet heads,
• Mai's snowballs and Yuki's fireballs,
• Yumeko's knives,
• and Shinki's 32×32 bullets.
But looking closer, it turns out that the fields of all these have very
different semantics, and in some cases, even different types. uth05win
treated all of those as distinct structures, and we're going to do the
same, merely overlaying the pointers onto the same generic array.
