The rendering infrastructure is set up to render a fullscreen quad. SDL_GPU is used as the rendering abstraction. The Metal backend is used on macOS, and the Vulkan backend on Windows. SDL_shadercross is used to compile/transpile HLSL shaders to SPIR-V and Metal. Shaders are compiled at build time and embedded as byte arrays into the source code. A window opens displaying the UV coordinates as the color.
