nmlgc c2fa1f3d3b [Maintenance] [th01] Use a common macro for sloppy unblitting of .PTN sprites
Part of P0158, funded by Yanga.

nmlgc 9739f69729 [Maintenance] Add a 1bpp rectangle template, for custom per-row types
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.

nmlgc d25daf7075 [Maintenance] Move the number of VRAM planes to pc98.h
Allowing us to consistently mirror the declaration in pc98.inc
without adding a planar.inc file. 😛 And points us to two more
dots8_t* arrays that should have used the Planar<> template.

nmlgc e8ae29ca4e [Maintenance] Remove the old `planar(8|16|32)_t` types
All code that used them has transitioned to C++, and can use the
Planar<> template.

nmlgc b974c1a915 [Maintenance] Add separate macros for GRCG/EGC-accelerated reads and writes
Not only getting rid of the "useless" (and thankfully, consistent)
bitplane parameter, but also allowing those shortened macros to be
redefined for the upcoming little ZUN inconsistency.

nmlgc ba29539fc7 [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…

nmlgc d6f634631f [Maintenance] Declare distinct types for pixel and VRAM sizes
Oh wait, we also need one of those for an upcoming structure!

nmlgc 368f151759 [Maintenance] Declare distinct types for screen, VRAM, and TRAM coordinates
Whew, time to look at every `int` variable we ever declared! The best
moment to do this would have been a year ago, but well, better late
than never. No need to communicate that in comments anymore.

These shouldn't be used for widths, heights, or sprite-space
coordinates. Maybe we'll cover that another time, this commit is
already large enough.

nmlgc bd1c2ee7de [Maintenance] #define the number of dots in a byte
One fewer magic number. And one more deliberate dependency on a
PC-98-specific hardware constant, to further drive home just how
unportable these games are, even once decompilation will be complete.

nmlgc d840841a2b [Naming] Rename egc_copy_rect_1_to_0() to emphasize its 16-dot alignment
ZUN might have gotten the impression that the EGC can *only* work with
multiples of 16 pixels per load or store? Which might explain why…

nmlgc f612c40dce [Maintenance] Move generic VRAM macros from REIIDEN.EXE's PTN code to planar.h
C++ templates would be *so nice* here, but code generation… 😢
