Detailed Description

Adaptative view.

An adaptative view is a view that adapts automatically to screen resolution change.

There are several kinds of adaptative views, according to the policy that is adopted when the resolution changes. In the examples below, The screen is represented by the black rectangle and the world is the red square. If red dashed lines appears, it means that the world has been modified.
