Class EXTCompositor
This extension allows for the composition of multiple windows within a multi-partition EGL system. The extension allows a primary EGLContext and window to be created for each display. All other windows are created using non-displayable surfaces. A handle to each off-screen window is provided to the primary EGLContext to allow the composition of all non-displayable windows on a single display.
For each display, there is one EGLContext which has access to create on screen windows, this is call the primary context for this display. All other EGLContexts are referred to as secondary contexts.
This extension requires a multi-partition EGL driver to support asynchronous rendering of off screen surfaces.
Information assurance is provided by preventing context and surface creation by unregistered contexts and by preventing the non-primary contexts and surfaces from rendering to the display.
