##Precision Pitfalls Between getRect and Width/Height##
Keep in mind when you are using
var boundingBox:Rectangle = mc.getRect(coordSystem)
or
var boundingBox:Rectangle = mc.getBounds(coordSystem)
the Rectangle returned will be of a greater precision than mc.x, mc.y, mc.width and mc.height
trace (mc.width == boundingBox.width)
will often return false.
Also keep in mind that getRect and getBounds also can return different results depending on the contents of the DisplayObject.
getBounds returns a rectangle that defines the area of the display object including lines and shapes
getRect returns the rectangle including the extra gurth added by outline strokes on shapes.
