These are used where the head or the feet of the player/enemy have to be
moved in an animation, and shouldn't overlap. These aren't actual GFX
and should be loaded with the proper commands, and they're always loaded
at the end of the VRAM area.
Furthermore, I've defined BATTLEANIM_BASE_TILE, which is the tile from
which battle animation graphics may start to load. This value was picked
to make sure at least an entire pokemon pic fits in the area before it,
even though it doesn't seem very used...
Tried simplifying things a bit, although not nearly as much as I wanted.
Ideally, we'd either have one of two situations:
- A single set of calculations based on values depending on the
direction of the connection
- A bunch of "generic" calculations done before applying simple
modifiers to them in the final `if` block
Right now it's an icky mix of both and I'm not really sure what to make
of it.
The previous name for this was rather misleading. It isn't an actual
jump like you'd expect the `jp` instruction to behave as. Instead, it
behaves more like a `farcall`.
This also makes it consistent with its current command ID name of
`TX_FAR`.
