Indicates that some progress has been made, but you don't know how much.
This causes the Gtk.ProgressBar to enter "activity mode," where a block bounces back and forth.
Each call to ProgressBar.Pulse() causes the block to move by a little bit (the amount of movement per pulse is determined by ProgressBar.PulseStep).
Requirements
