Introduces wrappers around memory allocation functions in `memory.h`
that should be used instead of the standard C ones.
These never return NULL and, with the exception of `mem_realloc()`,
zero-initialize the allocated memory like `calloc()` does.
All allocations made with the memory.h API must be deallocated with
`mem_free()`. Although standard `free()` will work on some platforms,
it's not portable (currently it won't work on Windows). Likewise,
`mem_free()` must not be used to free foreign allocations.
The standard C allocation functions are now diagnosed as deprecated.
They are, however, available with the `libc_` prefix in case interfacing
with foreign APIs is required. So far they are only used to implement
`memory.h`.
Perhaps the most important change is the introduction of the `ALLOC()`,
`ALLOC_ARRAY()`, and `ALLOC_FLEX()` macros. They take a type as a
parameter, and allocate enough memory with the correct alignment for
that type. That includes overaligned types as well. In most
circumstances you should prefer to use these macros. See the `memory.h`
header for some usage examples.
"Re-records" a replay into a file. TAISEI_REPLAY_DESYNC_CHECK_FREQUENCY
is defaulted to 1 in this mode, but may be overriden as normal. Requires
-r or -R; in case of -R will not stop even if a desync is encountered.

* Major refactoring of the main loop(s) and control flow (WIP)
run_at_fps() is gone 🦀
Instead of nested blocking event loops, there is now an eventloop API
that manages an explicit stack of scenes. This makes Taisei a lot more
portable to async environments where spinning a loop forever without
yielding control simply is not an option, and that is the entire point
of this change.
A prime example of such an environment is the Web (via emscripten).
Taisei was able to run there through a terrible hack: inserting
emscripten_sleep calls into the loop, which would yield to the browser.
This has several major drawbacks: first of all, every function that
could possibly call emscripten_sleep must be compiled into a special
kind of bytecode, which then has to be interpreted at runtime, *much*
slower than JITed WebAssembly. And that includes *everything* down the
call stack, too! For more information, see
https://emscripten.org/docs/porting/emterpreter.html
Even though that method worked well enough for experimenting, despite
suboptimal performance, there is another obvious drawback:
emscripten_sleep is implemented via setTimeout(), which can be very
imprecise and is generally not reliable for fluid animation. Browsers
actually have an API specifically for that use case:
window.requestAnimationFrame(), but Taisei's original blocking control
flow style is simply not compatible with it. Emscripten exposes this API
with its emscripten_set_main_loop(), which the eventloop backend now
uses on that platform.
Unfortunately, C is still C, with no fancy closures or coroutines.
With blocking calls into menu/scene loops gone, the control flow is
reimplemented via so-called (pun intended) "call chains". That is
basically an euphemism for callback hell. With manual memory management
and zero type-safety. Not that the menu system wasn't shitty enough
already. I'll just keep telling myself that this is all temporary and
will be replaced with scripts in v1.4.
* improve build system for emscripten + various fixes
* squish menu bugs
* improve emscripten event loop; disable EMULATE_FUNCTION_POINTER_CASTS
Note that stock freetype does not work without
EMULATE_FUNCTION_POINTER_CASTS; use a patched version from the
"emscripten" branch here:
https://github.com/taisei-project/freetype2/tree/emscripten
* Enable -Wcast-function-type
Calling functions through incompatible pointers is nasal demons and
doesn't work in WASM.
* webgl: workaround a crash on some browsers
* emscripten improvements:
* Persist state (config, progress, replays, ...) in local IndexDB
* Simpler HTML shell (temporary)
* Enable more optimizations
* fix build if validate_glsl=false
* emscripten: improve asset packaging, with local cache
Note that even though there are rules to build audio bundles, audio
does *not* work yet. It looks like SDL2_mixer can not work without
threads, which is a problem. Yet another reason to write an OpenAL
backend - emscripten supports that natively.
* emscripten: customize the html shell
* emscripten: force "show log" checkbox unchecked initially
* emscripten: remove quit shortcut from main menu (since there's no quit)
* emscripten: log area fixes
* emscripten/webgl: workaround for fullscreen viewport issue
* emscripten: implement frameskip
* emscripter: improve framerate limiter
* align List to at least 8 bytes (shut up warnings)
* fix non-emscripten builds
* improve fullscreen handling, mainly for emscripten
* Workaround to make audio work in chromium
emscripten-core/emscripten#6511
* emscripten: better vsync handling; enable vsync & disable fxaa by default
I would've preferred to just go with 4-spaces for indent and no tabs,
but lao is a bit conservative about it. :^)
Still, this is a ton better than mixing different styles all over the
place, especially within the same file.
