commit b2de61f5c5
Author: Andrei Alexeyev <akari@taisei-project.org>
Date:   Sat Dec 17 05:29:29 2022 +0100

    build: remove debug_opengl

    This option was always misdocumented, as it only controlled whether GL
    debugging is on by default. You can still control it with the
    TAISEI_GL_DEBUG environment variable, which is set to 1 in meson devenv.

commit 4c659ba195
Author: Andrei Alexeyev <akari@taisei-project.org>
Date:   Fri Dec 16 08:03:37 2022 +0100

    build: set up useful env vars for meson devenv

    Makes Taisei load resources from the source tree, making live reload
    work; enables OpenGL debugging by default; works around ASan stack use
    after return false positives.

commit 0c47f6d14b
Author: Andrei Alexeyev <akari@taisei-project.org>
Date:   Mon Dec 12 04:33:01 2022 +0100

    build: remove -Dversion_fallback and introduce .VERSION file

    The version script will now first try to read the version from a
    .VERSION file in the source root. If that file does not exist, it will
    query git. The .VERSION file is not included in the git repository, it
    is generated for inclusion in source tarballs.

    Package maintainers who had any use for -Dversion_fallback may want to
    create the .VERSION file themselves.

    Additionally, some git-specific files have been removed from source
    tarballs.

commit f9a3fbc729
Author: Andrei Alexeyev <akari@taisei-project.org>
Date:   Mon Dec 12 01:50:08 2022 +0100

    build: raise meson_version and remove some legacy workarounds

    Effectively 0.56.0 was already required since we started using some of
    its features at some point.

    This also fixes all current meson warnings.

Audio rewrite (#236)
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.

Implement Robin Hood hashing (#200)
* Implement Robin Hood hashing

This replaces the previous separate chaining implementation. This
approach is more memory-efficient, cache-friendly, and puts much less
stress on the memory allocator.

* Replace crc32 with fnva1

Also attempt to make the compiler pre-hash as much stuff as possible at
build time.

Switch audio assets to Opus (#167)
* Switch BGMs to Opus

* Switch SFX to Opus; use floating-point mixing

* opus sfx: support resampling via SDL_AudioStream

2.0.5 doesn't have the SDL_AudioStream API, and is ancient anyway.

e754dd54ba Some compatibility fixes for Elbrus compiler (and others based on EDG front end) (#157)
* Reduce alignment to 16 due to stack variables alignment
On some archs (e.g. elbrus) there is no possibility to align
variables on stack by more that 16 bytes.

* Added check for -Wno-typedef-redefinition
In C11, there is legal to redefine typedef with the same type,
but some compilers like elbrus's lcc and, probably, intel's icc
generate a warning about that. So we disable it.

* Typo fix

* Fix __builtin_unreachable() warning on some frontends like EDG

* Added check for __attribute__((designated_init))
It doesn't work for elbrus'c lcc and clang; but clang does not
generate warning by default, but we still disable it just in case.

* A hack to avoid -Wtype-limits for compilers with unsigned enums

* Rewritten unreachable __builtin_unreachable() behavior.
According to https://bugs.llvm.org/show_bug.cgi?id=13910,
old clang versions also suffer from this issue along with lcc.
And also this warning option is removed from gcc since 4.5.0,
and it's likely there is no unreachable code analysis at all:
https://gcc.gnu.org/onlinedocs/gcc-4.5.0/gcc/Warning-Options.html

* Fixed unneeded stray UNREACHABLE which caused warnings

* Removed alignas() which is unneeded after lowering alignment requirements

* Removed a hack of -Wunreachable-code disabling on certain compilers
Actually, there was a wrong opinion that most of unreachable code
warnings are produced by __builtin_unreachable() itself,
not the certain use of it. After commit 36493d3, it is finally
figured out that it wasn't the case.

* Added dummy element to a struct in a test for designated_init
This test will enexpectedly fail when GNU extensions are not available

add 'developer' option to decouple cheats etc. from build type
developer=true  --> DEBUG macro is set, regardless of build type
    developer=false --> DEBUG macro is not set, regardless of build type
    developer=auto  --> DEBUG macro is set only on debug* build types;
    this matches old behavior and is the default.

OpenGL ES 3.0 rendering backend (#148)
* First steps towards shader transpilation

Needs to be manually enabled via -Dshader_transpiler=true.

Requires shaderc. https://github.com/google/shaderc

Not yet functional due to missing SPIRV-Cross integration. SPIRV-Cross
currently does not have an official C API, and crossc is too minimal to
be useful. The current plan is to extend crossc and vendor it, while
also sending PRs upstream.

* Integrate crossc; shader transpilation for GLES now works

* fix leak

* gles30 backend now playable on Mesa with 3.2 context

Some rendering issues are present. Identified so far:
    - Marisa's lasers are invisible
    - Death effect looks wrong

Also, a small pixmap manipulation library has been written, and the
texture uploading API redesigned around it.

* fix marisa lasers in GLES (uniform name clashed with builtin)

* fix player death effect in GLES (another name clash)

* Dump ANGLE's translated shader code in debug log

* fix screenshots

* Drop support for triangle fans, switch to strips

Fans offer no advantage over strips, and they've been removed in D3D10+,
so ANGLE has to emulate them.

* crude workaround for an ANGLE bug

* Re-enable GL debug labels, fix an issue with them that affected ANGLE (but was always technically a bug)

* fix race condition in shaderc initialization

* New SDL_RWops interface for vertex buffers

* Optimize VBO streaming via buffering updates

Measurable performance improvement even with the main gl33 renderer,
drastic improvement with ANGLE.

* Fix the depth texture binding problem under ANGLE

Apparently it hates GL_DEPTH_COMPONENT16 for some reason. Sized internal
formats are not supported in GLES 2.0 anyway, so not using them is
probably a good idea.

* fix GLES2.0 segfault (the backend still doesn't work, though)

* dump GL extensions at info log level, not debug

* get around a Mesa bug; more correct texture format table for GLES2

* Correct GLES3 texture format table according to the spec

Not a Mesa bug after all

* require crossc>=1.5.0, fallback to subproject

* Request at least 8bit per color channel in GL backends

* Forbid lto for static windows builds with shader_transpiler=true

* fix edge case segfault

* Add basic ANGLE bundling support to the build system

Windows only, and no NSIS support yet

* Fix various windows-related build system and installer brokenness

* Disable gles backends by default

* update documentation
