Detailed Description

A View is a 2D area of a Layout.

It is a view of the application's data on a model, in the sense used by the MVC pattern. It can be a scene, viewing mode, viewing position, or any other representation of the application's data.

Warning
Never commit a View. Equalizer does take care of this to correctly associate view version with rendering frames.
