**☆ This will likely see breaking changes! Use at your own risk! ☆**
#### building
- Requires C++17 and CMake 3.14+
- A single *Platform* implementation must be enabled:
- [SDL2](https://github.com/NoelFB/blah/blob/master/src/internal/platform_sdl2.cpp) can be enabled in CMake with `BLAH_PLATFORM_SDL2` (default)
- [WIN32](https://github.com/NoelFB/blah/blob/master/src/internal/platform_win32.cpp) (UNFINISHED) can be enabled in CMake with `BLAH_PLATFORM_WIN32`
- Additional platforms can be added by implementing the [Platform Backend](https://github.com/NoelFB/blah/blob/master/src/internal/platform.h)
- At least one *Renderer* implementation must be enabled:
- [OpenGL](https://github.com/NoelFB/blah/blob/master/src/internal/renderer_gl.cpp) can be enabled in CMake with `BLAH_RENDERER_OPENGL`
- [D3D11](https://github.com/NoelFB/blah/blob/master/src/internal/renderer_d3d11.cpp) can be enabled in CMake with `BLAH_RENDERER_D3D11`
- Additional renderers can be added by implementing the [Renderer Backend](https://github.com/NoelFB/blah/blob/master/src/internal/renderer.h)
#### notes
- There's no Shader abstraction, so the [Sprite Batcher](https://github.com/NoelFB/blah/blob/master/src/graphics/batch.cpp) has hard-coded GLSL/HLSL. This will need to change.
- Only floatN/mat3x2/mat4x4 uniforms are supported.
- There's no Audio API or backend implementation yet.
- No threaded rendering so it will explode if you try that.
