Screen Graphics Subsystem

The Screen Graphics Subsystem is a compositing windowing system that can composite graphics from several different rendering technologies.

Diagram showing the different layers of the windowing system for devices.

Screen enables developers to create separate windows for the output of each rendering technology (for example, OpenGL ES). Each window can be transformed (for example, through scaling, translation, rotation, alpha blending, or other operations) to build the final scene for display.
