In _arb_vec_scalar_mul, _arb_vec_scalar_addmul, _acb_vec_scalar_mul, _acb_vec_scalar_addmul, we could add some case distinctions for special scalars, e.g. exact numbers of the form $\pm 2^e$ or $\pm 2^e i$, and also for low-precision intervals, etc. Also, the gr wrappers ought to wrap these (and other) arb, acb vector methods.
