Divides the foreground image into particles, and then blows the particles away directionally.
            
            Can optionally take a Background (Any). If no background clip is supplied, the foreground will be composited over black.
            
            Requires a Foreground (RGBA)
            
            Produces an Output (Any).

                        |   
                            | Sets the radius of the particles. Set any floating-point pixel value using the treadmill. | 
                     
                        |   
                            | Sets the space between the center of the original position of the particles. Set any floating-point pixel value greater than
                              2 using the treadmill.
                            | 
                     
                        |   
                            | Sets the wind speed. Set any floating-point pixel value using the treadmill. | 
                     
                        |   
                            | Sets the source direction of the wind. Set any floating-point value in degrees using the treadmill; 0 degrees is 3 0'clock,
                              positive values move counter-clockwise.
                            | 
                     
                        |   
                            | Sets the speed of the movement of the wind source. Set any floating-point value using the treadmill. | 
                     
                        |   
                            | Sets the air resistance; this controls how quickly a particle reaches the full speed of the wind. Set any floating-point value greater than 0.01 using the treadmill; the higher the value, the more quickly the particle will
                              reach the full speed of the wind.

                        |   
                            | Sets the bumpiness of the particles. Set a floating-point value between 0 and 1 using the slider. | 
                     
                        |   
                            | Sets the progression of the animation. Set any floating-point value using the treadmill. The larger the difference in the
                              time value between keyframes, the faster the effect will happen.
