Demonstrates the use of the aether effects library to alter a loaded image through the application of multiple effects combined through a CompositeEffect. 

  
          public class @ax-graphic-flex-image-effects-07-Flex-AetherTest extends graphic_flex_image_effects_07_Flex_AbstractImageLoader {
Constructor. Passes path of image to load to super class. 

  
                  public function @ax-graphic-flex-image-effects-07-Flex-AetherTest() {

                  }
Run after the image loads in super class. This adds the image to the stage, then dupes it and applied a number of combined effects to the dupe using aether before adding the dupe below the original.
