x/mobile: exp/sprite lacks point -> sprite mapping function?

[lavalamp]

What version of Go are you using (go version)?

1.9

What did you do?

Played with the exp/sprite package

What did you expect to see?

A mechanism for taking a point (e.g., from touch.Event) and identifying a sprite or list of sprites which contain that point.

What did you see instead?

No mention of such a thing in the documentation or code. Seems like 50% of the functionality of a sprite engine?

I wonder if that's where they got the name for the Sprite Operating System.
