Request that a rectangle of this view be visible on the screen, scrolling if necessary just enough.

A View should call this if it maintains some notion of which part of its content is interesting. For example, a text editing view should call this when its cursor moves.

The Rectangle passed into this method should be in the View's content coordinate space. It should not be affected by which part of the View is currently visible or its scroll position.
