nmlgc 97ce07bfc9 [Reverse-engineering] [th03] CDG: VRAM plane iteration
Which is where ZUN adds those additional 0x2000 to make the jump from
the 0xB800 plane to the 0xE000 plane.

nmlgc 0f3359e1b3 [Maintenance] Use @@locals for self-modifying code in bfnt_entry_pat()
Which finally allows us to use the PLANE_SIZE macro in ASM land. Yeah,
(ROW_SIZE * RES_Y) has finally got old.

nmlgc 4340b5d6ae [Maintenance] [th01/th02] Split graph_putsa_fx() into its shared parts
I did consider not doing this, because "well, can't anyone who's
*actually* interested just diff the TH01 and TH02 implementations to
figure out the differences themselves", but that duplication ended up
feeling too filthy after all.

And hey, it's a nice excuse to update TH02's version to current naming
standards! 😛

nmlgc 0e19e52572 [Maintenance] Templatize RGB and palette types for 4- and 8-bit components
Right, PC-98 hardware only supports 4 bits per RGB component, for a
total of 4,096 possible colors. The 8-bit RGB color values we've been
seeing throughout the later games are a master.lib extension, to allow
for more toning precision. Which TH01, with all its NIH syndrome,
doesn't use.

And yup, that means templates in the most basic header files… Since
that would have meant renaming *everything* to compile as C++, I simply
made these types exclusive to C++ code, thcrap style.

nmlgc 8b01c60f44 [Maintenance] Move PC-98 hardware constants to a separate include file
SPRITE16 would also like to refer to those later.
