// Draws a rectangle that has smooth round corners for a given "smoothness"
// value between 0.0 and 1.0 (representing 0% to 100%).
//
// The smoothness value determines how much edge length can be consumed by each
// corner, scaling with respect to that corner's radius. The smoothness will
// dynamically scale back if there is not enough edge length, similar to how
// the corner radius backs off when there isn't enough edge length.
//
// Each corner's radius can be supplied independently. Corner radii are expected
// to already be balanced (Radius1 + Radius2 <= Length, for each given side).
//
// Elliptical corner radii are not currently supported.
