// A progress bar that carries both of the modes this application needs, so the
// two places that show one do not each configure a bare QProgressBar. The
// status bar's sync indicator is indeterminate, because mbsync reports no
// percentage; the composer's send popup drains a determinate bar through its
// undo countdown and then switches THE SAME widget to indeterminate when the
// command starts. That switch is why one class exists rather than two.
//
// Deliberately no label. MainWindow's status text is m_statusLabel, which is
// the window's and carries far more than this widget's state, and the send
// popup's phase text belongs to the popup. A label here would be a third
// owner of status text.
