Second PC-98 Touhou boss completely decompiled, 29 to go! But meh,
ZUN's original code did in fact force the three leaf pattern sprites
into separate 1-sprite sheets…

The one where Sariel's second form shoots sparks towards the top of the
playfield, which then turn into leaf-like sprites that sway towards the
bottom, killing Reimu on contact.
And wow, what a finish! A weird "decimal subpixel" type, hardcoded
sprites, and effectively unused non-hardcoded sprites. Too bad that it
also ruins the nice `dot_rect_t(w, h)` parameter abstraction for
grcg_put_8x8_mono()…
