// A key requirement is that since many ruy files, including public headers,
// need a definition of Ctx, the "ctx.h" header defining it must minimize how
// many other ruy internal headers it includes. That is achieved by putting data
// members in the CtxImpl subclass, and ensuring that only a few .cc files, not
// header files, need a definition of CtxImpl.
