Axmol-v3 Roadmap

[halx99]

• ISO c++23 standard
• Implement d3d11 RHI
• Texture resource improvment, add texture array support, remove CPU array implement since all graphics API support texture array
• Remove sampler from Texture, implement texture sampler object and cache it, since GLES3/OGL-3.3, mtl, d3d support sampler object
• Update lua to 5.5.x
• Remove the default pixel format, fix rendering of grayscale PNGs by @j-jorge in Remove the default pixel format, fix rendering of grayscale PNGs #2573
• Remove all deprecated stubs
• Implement drawArraysInstanced and make instanced draw more common use
• box2d-3.x
  • Make Box2dTest of cpp-tests works on box2d v3
  • Make Box2dTestBed of cpp-tests works on box2d v3
• Remove chipmunk
  • Remove core/physics based on chipmunk
  • Remove ChipmunkTest from cpp-tests
  • Remove ChipmuniTestbed from cpp-tests
• Improve DrawNode, don't create backend::Buffer always
• Upgrade iOS deploy target: 12.0 => 13.0
• Upgrade android minsdk: 17(Android 4.2) => 21(Android 5.1)
• Upgrade android ndk: r23 => latest LTS release r27
• Due to android,ios toolchain update to support c++20 full features, std::views::split can be use to improve performance
• Remove 3rdparty ghc filesystem, since both ios13 and android5.1 support std::filesystem
• Build and run wasm64 support, current need enable chrome flag: chrome://flags/#enable-webassembly-memory64
• Color4B => Color32
• Remove Color3B
• Remove deprecated StringUtils::format
• drop GLES 2.0 support since all Android 5.1+ devices support opengl-es-3.0
• Improve axslcc preprocessors, remove METAL, GLES2, then add AXSLC_TARGET_[GLSL,HLSL,MSL,GLES]
• Improve VertexLayout management
• Improve sampler2D texs[4] support, 2.x only support OpenGL, now support all RHI: d3d11, metal, opengl(es)
• Reimplement core/physics with box2d v3, not all API compatible with axmol-2.x (in-progress)
  • basic functionals
  • Rename PhysicsJointXXX::construct => PhysicsJointXXX::instantiate
  • b2ContactListener
• re-select json lib: yyjson > boost.json > rapidjson
  simdjson for parse only and simdjson build in-progress: https://github.com/simdjson/experimental_json_builder
  finally solution: yyjson + simdjson
• drop tolua, use sol2
• Choose shader for more render objects like Sprite
  • ParticleSystemQuad
