Draw an arc. This will draw an arc with the current pen. The arc is a section of an oval starting at the start angle, with 0 being at the noon position, 90 is at the 3 o'clock position. 45 is at a line drawn from the center of the rectangle through the top, right corner. The length of the arc is defined by the srcAngle defining how many degrees the arc covers. A negative number goes counter-clockwise.
