NAME
    Animation.Raster -- Virtual Raster Scrolling Animation

SYNOPSIS
        var ras = new Animation.Raster( id_or_elem, image_url );
        ras.lineHeight  = 6;                    // scroll line's height
        ras.clip        = true;                 // clip animation area (default: true)
        ras.background  = "#000000";            // animation area's background
        ras.downSeconds = 1.0;                  // falling down animation
        ras.fadeSeconds = 4.0;                  // fading wave animation
        ras.waveSpeed   = 0.5;                  // wave's speed
        ras.onComplete  = function () { ... };  // callback function
        ras.scroll();

DESCRIPTION
    This library provides a animation effect of virtual raster scrolling for
    images and block elements.

METHODS
  ras = new Animation.Raster( id_or_elem, image_url );
    This constructor method returns a new Animation.Raster object. The first
    argument is the animation's container element or its id string. The
    second argument is the target image's URL for raster scrolling. If URL
    is not defined, container element itself is animated.

  ras.scroll();
    This method starts a animation effect.

  ras.finish();
    This method forces to stop a animation effect if it's running.
