Original change's description:
> Fix rendering of drrects with small circular inner rrects.
> 
> Previously when the inner rrect was a circle with a radius of 1 we would
> cause a inf * 0 in the shader which would lead to the shape not rendering.
> 
> This change also makes concentric circle drrects draw as stroked circles.
