Description:

  This module is a C coroutine that presents a special X-window
  with a large dial. The dial is similar to the standard AVS
  dial widget, but has higher resolution and a secondary needle
  that moves much slower than the primary needle.
  The dial can work in accumulator mode (around and around)
  or with fixed low and high end stops. In immediate mode
  it sends an output float to the output port continuously
  while the needle is moving, otherwise only when the mouse
  button lifts up.
