-/**
- * This struct contains all state used to generate the GLSL shader program that emulates the current
- * Pica register configuration. This struct is used as a cache key for generated GLSL shader
- * programs. The functions in gl_shader_gen.cpp should retrieve state from this struct only, not by
- * directly accessing Pica registers. This should reduce the risk of bugs in shader generation where
- * Pica state is not being captured in the shader cache key, thereby resulting in (what should be)
- * two separate shaders sharing the same key.
- *
- * We use a union because "implicitly-defined copy/move constructor for a union X copies the object
- * representation of X." and "implicitly-defined copy assignment operator for a union X copies the
- * object representation (3.9) of X." = Bytewise copy instead of memberwise copy. This is important
- * because the padding bytes are included in the hash and comparison between objects.
