[Feature] center image in sunburst

[nphias]

What problem does this feature solve?

i noticed on all examples of sunburst charts.. the zoom out middle button is a blue circle.
i would like to swap that for an image of my choosing, preferable with some on-click animation

What does the proposed API look like?

provide the option in the sunburst config.. or give an example of how to hack this

oh yes, it is hacky to place an image in there - Demo. However the image layout is repeat: 'repeat', which you probably do not want.
Would be nice to have repeat: 'no-repeat' (single image) with responsive positioning like CSS background-position: center;, but that is not currently available in API.
A nice new feature candidate for v.6.0 though! Looks like the object to enhance is PatternObjectBase
