Number

    EGL Extension #XXX

Dependencies

    Requires EGL 1.2

    This extension is written against the wording of the EGL 1.5 Specification

Overview

    This extension is intended for latency-sensitive applications that are doing
    front-buffer rendering. It allows them to indicate to the Android compositor
    that it should perform composition every time the display refreshes. This
    removes the overhead of having to notify the compositor that the window
    surface has been updated, but it comes at the cost of doing potentially
    unneeded composition work if the window surface has not been updated.

    doing front-buffer rendering.
