* Add red fairies; tweaks to blue fairies and circles
* Add more fairies and a simple enemy archetype system
Note that existing stages not utilizing the new enemy spawning system
will have a visual regression - fairies will not have their magic
circles and particle effects visible. These are no longer implemented by
the enemy visual rules and require additional setup from the new spawner
wrappers. All stages should be converted to the new system.
Also improved old fairy sprites

This replaces SDL_mixer with an internal streaming and mixing system,
relying only on basic SDL audio support. It's also a partial refactor of
the audio API, most notably BGM-related. The BGM metadata resource type
is gone, as well as the `.bgm` files. The metadata is now stored inside
the `.opus` files directly, using standard Opus tags.
http://sauerbraten.org/iqm/
The iqms were converted from the objs with the official iqm "compiler",
but can be also exported directly from Blender with a script from the
SDK.
In addition, indexed rendering was fixed (it's not useless anymore), and
the winding order convention changed from counter-clockwise to clockwise
to facilitate faster model loading.
A limited subset of IQM functionality is currently supported:
- One mesh per model.
- Only floating point data in vertex arrays.
- Only standard vertex arrays: positions, UVs, normals,
tangents.
- No animations etc.
The "standard" shader interface now receives an additional vec4 tangent
attribute. This attribute is currently ignored by shaders. The bitangent
vector can be computed in a vertex shader as:
vec3 bitangent = cross(normal, tangent.xyz) * tangent.w;
* iqm: remove axis scrambling and re-export models
* remove debug stuff
If "linearize = true" is specified in the .tex file, colors will be
converted from the sRGB color space into the linear RGB color space on
load. Ideally this should be the default, and we should be doing all
color manipulations in linear space, but there's too many things to fix
to make that a reality.
Additionally, "multiply_alpha = false" to prevent colors from being
multiplied by the alpha channel on load.
The texture_post_load shader will no longer be applied when the
preprocessing operation is a no-op.

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: implement frameskip
* emscripter: improve framerate limiter
* align List to at least 8 bytes (shut up warnings)

* Workaround to make audio work in chromium
emscripten-core/emscripten#6511

* Once again separated ZIP support from data packaging
* Converted macOS cross-compilation options into cross-file properties
