// remainder to try to fill the next one as well.
// The tx size if roughly estimated as a linear function of only inputs, and a
// new tx will be created when that size goes above a given fraction of the
// max tx size. At that point, more outputs may be added if the fee cannot be
// satisfied.
// If the next output in the next tx would go to the same destination (ie, we
// cut off at a tx boundary in the middle of paying a given destination), the
// fee will be carved out of the current input if possible, to avoid having to
// add another output just for the fee and getting change.
// This system allows for sending (almost) the entire balance, since it does
// not generate spurious change in all txes, thus decreasing the instantaneous
// usable balance.
