  //     frame:          As usual.
  //     gradientColors: Array of colors to create the background gradient. It can be any number of
  //                     UIColor objects, although less colors generate better results. If a single
  //                     color is used, the progress view will be drawn with no gradient. If 'nil' is
  //                     passed, a standard red to yellow to green gradient is generated automatically.
  //     outsideBorder:  Sets if the progress view has (YES) or not (NO) a border.
  //     vertical:       Sets if the progress view is vertical (YES) or horizontal (NO).
