           Angle1 - first angle
           Angle2 - second angle
  Returns: Whether the call was successful

  Use Arc to draw an elliptically curved line with the current Pen.
  The angles angle1 and angle2 are 1/16th of a degree. For example, a full
  circle equals 5760 (16*360). Positive values of Angle and AngleLength mean
  counter-clockwise while negative values mean clockwise direction.
  Zero degrees is at the 3'o clock position.
