If I was to use some sort of Boost.GUI it would be to implement a 
zooming interface.

The ideal library would allow user customization to account for non 
traditional interfaces. I don't think we want to be stuck with a library 
that can't be modified/expanded in the future.

For a zooming-ui there would need to be some form of non 2D aspect. Like 
Z or Layer component. So making sure that one can 
redefine/replace/customize the actual definitions of these base types 
would be essential.

Definitely. As it would make it that much more useful to others if they 
case use those parts independently.
