How feasible is it to implement a reference software GPU?

Textures

On-the-fly format conversion to native floats

but it's easier to debug.

There is always something like SwiftShader https://github.com/google/swiftshader

But I'm not sure that it would help with debugging, and would likely just result in low quality issues raised by people with underpowered computers (i.e. no GPU) complaining about performance.
