-	VERSION: Drop Shadow jQuery Plugin 1.6  12-13-2007
-
-	REQUIRES: jquery.js (1.2.6 or later)
-
-	SYNTAX: $(selector).dropShadow(options);  // Creates new drop shadows
-					$(selector).redrawShadow();       // Redraws shadows on elements
-					$(selector).removeShadow();       // Removes shadows from elements
-					$(selector).shadowId();           // Returns an existing shadow's ID
-
-	OPTIONS:
-
-		left    : integer (default = 4)
-		top     : integer (default = 4)
-		blur    : integer (default = 2)
-		opacity : decimal (default = 0.5)
-		color   : string (default = "black")
-		swap    : boolean (default = false)
-
-	The left and top parameters specify the distance and direction, in	pixels, to
-	offset the shadow. Zero values position the shadow directly behind the element.
-	Positive values shift the shadow to the right and down, while negative values 
-	shift the shadow to the left and up.
-	
-	The blur parameter specifies the spread, or dispersion, of the shadow. Zero 
-	produces a sharp shadow, one or two produces a normal shadow, and	three or four
-	produces a softer shadow. Higher values increase the processing load.
-	
-	The opacity parameter	should be a decimal value, usually less than one. You can
-	use a value	higher than one in special situations, e.g. with extreme blurring. 
-	
-	Color is specified in the usual manner, with a color name or hex value. The
-	color parameter	does not apply with transparent images.
-	
-	The swap parameter reverses the stacking order of the original and the shadow.
-	This can be used for special effects, like an embossed or engraved look.
-
-	EXPLANATION:
-	
-	This jQuery plug-in adds soft drop shadows behind page elements. It is only
-	intended for adding a few drop shadows to mostly stationary objects, like a
-	page heading, a photo, or content containers.
-
-	The shadows it creates are not bound to the original elements, so they won't
-	move or change size automatically if the original elements change. A window
-	resize event listener is assigned, which should re-align the shadows in many
-	cases, but if the elements otherwise move or resize you will have to handle
-	those events manually. Shadows can be redrawn with the redrawShadow() method
-	or removed with the removeShadow() method. The redrawShadow() method uses the
-	same options used to create the original shadow. If you want to change the
-	options, you should remove the shadow first and then create a new shadow.
-	
-	The dropShadow method returns a jQuery collection of the new shadow(s). If
-	further manipulation is required, you can store it in a variable like this:
-
-		var myShadow = $("#myElement").dropShadow();
-
-	You can also read the ID of the shadow from the original element at a later
-	time. To get a shadow's ID, either read the shadowId attribute of the
-	original element or call the shadowId() method. For example:
-
-		var myShadowId = $("#myElement").attr("shadowId");  or
-		var myShadowId = $("#myElement").shadowId();
-
-	If the original element does not already have an ID assigned, a random ID will
-	be generated for the shadow. However, if the original does have an ID, the 
-	shadow's ID will be the original ID and "_dropShadow". For example, if the
-	element's ID is "myElement", the shadow's ID would be "myElement_dropShadow".
-
-	If you have a long piece of text and the user resizes the	window so that the
-	text wraps or unwraps, the shape of the text changes and the words are no
-	longer in the same positions. In that case, you can either preset the height
-	and width, so that it becomes a fixed box, or you can shadow each word
-	separately, like this:
-
-		<h1><span>Your</span> <span>Page</span> <span>Title</span></h1>
-
-		$("h1 span").dropShadow();
-
-	The dropShadow method attempts to determine whether the selected elements have
-	transparent backgrounds. If you want to shadow the content inside an element,
-	like text or a transparent image, it must not have a background-color or
-	background-image style. If the element has a solid background it will create a
-	rectangular	shadow around the outside box.
-
-	The shadow elements are positioned absolutely one layer below the original 
-	element, which is positioned relatively (unless it's already absolute).
-
-	*** All shadows have the "dropShadow" class, for selecting with CSS or jQuery.
-
-	ISSUES:
-	
-		1)	Limited styling of shadowed elements by ID. Because IDs must be unique,
-				and the shadows have their own ID, styles applied by ID won't transfer
-				to the shadows. Instead, style elements by class or use inline styles.
-		2)	Sometimes shadows don't align properly. Elements may need to be wrapped
-				in container elements, margins or floats changed, etc. or you may just 
-				have to tweak the left and top offsets to get them to align. For example,
-				with draggable objects, you have to wrap them inside two divs. Make the 
-				outer div draggable and set the inner div's position to relative. Then 
-				you can create a shadow on the element inside the inner div.
-		3)	If the user changes font sizes it will throw the shadows off. Browsers 
-				do not expose an event for font size changes. The only known way to 
-				detect a user font size change is to embed an invisible text element and
-				then continuously poll for changes in size.
-		4)	Safari support is shaky, and may require even more tweaks/wrappers, etc.
-		
-		The bottom line is that this is a gimick effect, not PFM, and if you push it
-		too hard or expect it to work in every possible situation on every browser,
-		you will be disappointed. Use it sparingly, and don't use it for anything 
-		critical. Otherwise, have fun with it!
