This is a perfectly fine generic sprite blitting function. Why doesn't
this game have more of these?

-												[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…

This gets rid of a couple of per-entity sprite bitplane types, makes
sprite declarations easier to read by putting width and height next to
each other… and points out a number of array dimension mistakes -.-
Even in places where we can't use it.
