Screen Graphics Subsystem

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 (e.g., OpenGL ES) so that each window can be transformed (e.g., scaling, translation, rotation, alpha blending, etc.) to build the final scene for display.
