The Rect class is a filled graphic element that draws a rectangle. The corners of the rectangle can be rounded. The drawElement() method calls the Graphics.drawRect() and Graphics.drawRoundRect() methods.

Note: By default, the stroke of the border is rounded. If you do not want rounded corners, set the joints property of the stroke to JointStyle.MITER.

	`width:Number` — The element's bounds width, or NaN to use the preferred width.

	`height:Number` — The element's bounds height, or NaN to use the preferred height.

	`postLayoutTransform:Boolean` (default = `true`) — When `postLayoutTransform` is true, the method returns x coordinate of the element's bounding box top-left corner. The bounding box is in element's parent coordinate space and is calculated from the specified bounds size, layout position and layout transform matrix.
