Detailed Description

Screen view.

This view will always match the window size which means that no scaling happens and no black bars appear. As a disadvantage this means that the gameplay might change, because a player with a bigger framebuffer might see more of the game, than a player with a smaller framebuffer size.

This view can be used to display HUD.
