Parameters
x1,y1 : current position (pixel)
x2,y2 : control point 1 (pixel)
x3,y3 : control point 2 (pixel)
x4,y4 : next position (pixel)
t1,t2 : start and end time. the times are relative to the start time of the syllable (millisecond)
accel : 1 the animation speed to be linear . 0 ＜ 1 the animation to start fast and end slow . 1 ＜ the animation to start slow and end fast.(the speed is influenced also by the position of the control point. )
afterimage_blur : the range of the afterimage moves (pixel)
afterimage_dur : the duration of the afterimage moves (millisecond)
density : the drawing number of times per one frame
