Looking for a word that defines both size and position

I am developing an application and can not figure out a proper abstract term that would fit an interface that defines an object as Movable and Resizable (In essence, something that has a defined size and defined position).

Calling it Movable and resizable is kind of silly.
Layout was a term that came to my mind but it is not good as layout is something that is responsible for defining position and size, not containing it.

Thanks a lot.
