  Method:  Arc
  Params:  DC - handle to device context
           Left - x-coordinate of bounding rectangle's upper-left corner
           Top - y-coordinate of bounding rectangle's upper-left corner
           Right - x-coordinate of bounding rectangle's lower-right corner
           Bottom - y-coordinate of bounding rectangle's lower-right corner
           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.

{------------------------------------------------------------------------------
  Method:   AngleChord
  Params:   DC, x1, y1, x2, y2, angle1, angle2
  Returns:  Nothing

  Use AngleChord to draw a filled Chord-shape on the canvas. 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.
