// As a matrix multiplication library, Ruy offers a Mul entry point, performing
// matrix multiplication. For implementation purposes, it is much nicer to
// be dealing with the transpose-and-multiply operation, doing
//   Destination = Transpose(LHS) * RHS
// Indeed, the latter is performing dot-products between the *columns* of LHS
// and the columns of RHS, whereas a plain matrix multiplication is performing
// dot-products between the *rows* of LHS and the columns of RHS.
// That is why TrMul is nicer to implement, allowing for a more symmetric
// treatment of LHS and RHS.
