The usual way to use this is via breezy.ui.ui_factory.nested_progress_bar which
will manage a conceptual stack of nested activities.

If this returns true we expect that a human may be looking at that
output, and that we can repaint a line to update it.
This doesn't check the policy for whether we *should* use them.

dS )� ProgressTaskaq Model component of a progress indicator.
Most code that needs to indicate progress should update one of these,
and it will in turn update the display, if one is present.
Code updating the task may also set fields as hints about how to display
it: show_pct, show_spinner, show_eta, show_count, show_bar. UIs
will not necessarily respect all these fields.
The message given when updating a task must be unicode, not bytes.
:ivar update_latency: The interval (in seconds) at which the PB should be
updated. Setting this to zero suggests every update should be shown
synchronously.
:ivar show_transport_activity: If true (default), transport activity
will be shown when this task is drawn. Disable it if you're sure
that only irrelevant or uninteresting transport activity can occur
during this task.

dS )a� Construct a new progress task.
:param parent_task: Enclosing ProgressTask or None.
:param progress_view: ProgressView to display this ProgressTask.
:param ui_factory: The UI factory that will display updates;
deprecated in favor of passing progress_view directly.
Normally you should not call this directly but rather through
`ui_factory.nested_progress_bar`.

DummyProgressaV Progress-bar standin that does nothing.
This was previously often constructed by application code if no progress
bar was explicitly passed in. That's no longer recommended: instead, just
create a progress task from the ui_factory. This class can be used in
test code that needs to fake a progress task for some reason.
