Show/Hide Layers

In the Compass Travel example, one can put each image description in a separate layer, and then use a show/hide layers behavior for each circular button on the left so that the only layer visible during the mouse over is the correct image description.  However, in the Compass Travel case, one could just use a Swap Image behavior associated with the mouseover of one of the left buttons to change two images, one image for the button and another image for the associated description.  The latter solution is far simpler since one doesn't have to worry about using layers and having the 5 layers on top of each other positioned in the same location.  However, in other cases, the show/hide layers behavior provides capabilities not available through the Swap Image behavior.  Examples would include where one has text to display during the mouseover rather than an image.
