When placing a hitbox around a shape, I use 'impose' to 'forget' the envelopes of the hitbox in further calculations:
impose hitbox shape
However, onClick messages on this shape do not work anymore, since hitbox is placed on top of it.
I would love to see a feature that works like 'impose', but keeps the the envelopes of the fore.
After some experimenting, it appears that the most common use case for impose is to use the foreground and forget the background. I will change this in the next major version.
