// Using the `canvas` this function paints a half-full/half-dotted ring at
// `ring_bounds`, which is also used to determine where the ring is painted.
// Used to draw pending/inactive states around circular icons. A common pattern
// for this usage is to shrink the desired icon and then draw the dotted path
// using the original icon bounds.
// `opacity_ratio` is expected to have a value between 0.0 and 1.0, otherwise it
// will clamped. It can be used with animation current value to fade in the
// ring.
// `stroke_width` is the width of the ring.
