pick nits from example bounding_2d (#12563)

Browse Source 
# Objective

- went through bounding_2d example with a fine-toothed comb and found
two small issues

## Solution

- pulled "draw a small filled-in circle" logic into a function
- removed impotent addition of aabb / circle origin (identically
`Vec2(0.0, 0.0)`)
