nmlgc deb1b73016 [Maintenance] Use a single DEFCONV definition file to cover all games 
This makes a lot more sense in C land, where we can then #include this
tiny file in front of all DEFCONV declarations.

nmlgc 417ba80c00 [Decompilation] Add a separate segment type 
At least wherever Turbo C++ and master.lib want us to use a
non-pointer, since both use uint16_t for segment values throughout
their APIs instead of the more sensible void __seg*. Maybe, integer
arithmetic on segment values was widely considered more important than
dereferencing?

nmlgc 9cb6cc527a [Decompilation] Finally declare <stdint.h> types 
*Finally*. We already used `(unsigned) int` in quite a few places where
we actually want a 16-bit value, which was bound to annoy future port
developers.

Fine, let's drag that ASM slice along, instead of immediately reusing
the already decompiled TH02 version… The website really needs a
decompilation metric soon, anyway. --Nmlgc

wintiger0222 38e8fd6a8d [Reverse-engineering] [th04/th05] Music Room / ending background image buffers 
"bgimage" really was the best name I could come up with here, given
what it's used for. Everything else sounded way too ambiguous. Even
something like "mempage", in the meaning of "a third memory-backed
graphics page"… --Nmlgc

wintiger0222 9684cf5312 [Reduction] [th03] Music Room comment back buffer 
I think cmt_back_* type functions need more universal name
Because at th04 and th05, it used in zunsoft opening animation
--WindowsTiger

And in MAINE.EXE. So I agree for TH04 and TH05, but TH03 still only
allocates, snaps, and recovers only the VRAM area occupied by the music
comments. --Nmlgc

wintiger0222 2a722db215 [Reverse-engineering] [th05] Music Room piano functions 
No need to declare most of these in C land if 1) it isn't even clear
yet whether we can even decompile these functions with their 2)
complex __usercall conventions, which 3) aren't even called from
outside this slice. --Nmlgc

nmlgc 5f4f5d87dc [Decompilation] [th03] Shot update and render functions 
Meh, can't overload arithmetic operators that take a Subpixel without
generating a needless load and store, even with -Z. But heck, slightly
uglifying subpixel/subpixel arithmetic is exactly the right trade-off.
