  	VERSION: Drop Shadow jQuery Plugin 1.6  12-13-2007
  
  	REQUIRES: jquery.js (1.2.1 or later) and jquery.dimensions.js
  
  	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!
