Question on SDL_CompileFromSPIRV and SDL_GpuCreateShader about sdl_gpu_examples HOT 2 CLOSED

It's not obvious due to the naming scheme, but SDL_CompileFromSPIRV is provided via the SDL_gpu_shadercross single-header library, which is a satellite library and not part of SDL_Gpu proper. (It used to be part of SDL_Gpu, but we removed it after the maintainers requested that we not rely on any specific external library like SPIRV-Cross. We'll probably end up changing the name to prevent future confusion.)

The only officially-provided way to set up shader data is to use SDL_GpuCreateShader with your shader bytecode data (generated either via offline shader compilers or some runtime shader cross-compilation pipeline). This allows for maximum flexibility for varying shader pipelines and is ultimately what's getting called inside of SDL_CompileFromSPIRV.
