In order to allow chips to be properly drawn when they expand in size (without using IntrinsicHeight), I needed a BoxDecoration shape that would be dependent upon the rendered height of the widget. This seemed to be pretty generally useful, so I added a new ShapeDecoration called StadiumBorder. It uses the minimum dimension to adjust the BorderRadius of a rounded rect in the shape decoration. I also converted some uses of BoxShape to be case statements, updated the chips to use the StadiumBorder decoration, and updated some of the metrics to match the Material spec, as well as implementing lerping to and from StadiumBorder.
