				File Summary: FExampleCircle.cpp

   Creates a one frame movie containing a circle with:
   
	1) blue solid fill color,
	2) a standard 1 pixel wide, black line.

	//Each SWF tag in the movie will be represented by an FObj
	FObjCollection allTags;


// Construct first flash tag object (set background color):

	//define a color for the background
	const FColor white(0xff, 0xff, 0xff);

	allTags.AddFObj(background);


//Now start creating the circle object. You must:
	//Create the bounds rect
	//Create the Shape Record and remember its ID
	//Create the Color for the fill
	//Create the Fill
	//Add the fill to the shape
	//Create the color for the circle's line style
