  Description:  Does not resample.

  Arguments:    selectedPoints, pSelectedPointNum: Pointers that return the results.
                maxPointCount   Upper limit of input points (includes stylus up marker)
                maxStrokeCount      Upper limit of stroke count
                strokes             Raw input coordinate value before forming
