This allows for more easily updating the CornerSize independently from the CornerTreatment and makes it possible to create different types of CornerSizes such as percentage based corners. However, this means corner sizes can be different depending on the bounds of the shape, so the bounds need to be provided. MaterialShapeDrawable has bounds and the ShapeAppearanceModel, so there are new convenience methods there which return the current corner size for the current bounds of the drawable.
