| * The ColorMatrixFilter class lets you apply a 4 x 5 matrix transformation on the |
| * RGBA color and alpha values of every pixel in the input image to produce a result |
| * with a new set of RGBA color and alpha values. It allows saturation changes, hue |
| * rotation, luminance to alpha, and various other effects. You can apply the filter |
| * to any display object (that is, objects that inherit from the DisplayObject class), |
| * such as MovieClip, SimpleButton, TextField, and Video objects, as well as to |
| * BitmapData objects. |
