No, the struct being compared is poorly named & collides with a CSO
entity. It's really all the state which the compiled fragment shader
will reference when it is later invoked. It's all packed into a single
struct because it's easier to pass a single parameter to llvm-compiled
shaders and add/change that parameter, but it is somewhat non-orthogonal
and we end up generating too many of them.
