  // Description:
  // Determine the size and placement of any tick marks to be rendered.
  //
  // This method must set this->P->TickBox.
  // It may depend on layout performed by ComputeScalarBarLength.
  //
  // The default implementation creates exactly this->NumberOfLabels
  // tick marks, uniformly spaced on a linear or logarithmic scale.
  //
  // It centers labels on color swatches instead of placing labels
  // at the edge.
