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
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.
* fixing OpenGL ES 3.0 support in macOS
* make GLES libraries loaded via buildconf vars
* fix relative install paths for macOS
* fix indenting, add comments
* fix indentation for REAL this time (thanks editorconfig)
Controls treatment of warnings caused by attr_deprecated.
Can be one of the following values:
* default: No special treatment.
* error: Always treat as errors, regardless of the werror option.
* no-error: Never treat as errors, regardless of the werror option.
* ignore: Suppress the warnings.
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.
* Added (and fixed) a few useful warnings
* Removed some dead code
* Cleaned up the build system files a bit
* Once again separated ZIP support from data packaging
* Converted macOS cross-compilation options into cross-file properties
* 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
