[Decompilation] [th01] Unaligned monochrome 8×8 sprite blitting This is a perfectly fine generic sprite blitting function. Why doesn't this game have more of these? Part of P0105, funded by Yanga.

[Maintenance] Declare a distinct type for VRAM offsets … and this one, while I'm at it. I've been using pretty much every possible type for VRAM offset variables, depending on my mood that day, since signedness apparently never matters for those. Except that it does. And so, just like with most of our high-level types, we also have to account for ZUN's little signedness inconsistencies here. Oh well, at least it's now only one of two types, and there's no need to choose between `int` or `unsigned int` or `short` or `unsigned short` or `int16_t` or `uint16_t` or `size_t` or… Part of P0111, funded by [Anonymous] and Blue Bolt.

[Decompilation] [th01] Sariel: Pattern 16/16 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()… Completes P0180, funded by Yanga.
