Composite Extension

The Composite Extension of the X Window System renders the graphical output of clients "...to an off-screen buffer. Applications can then take the contents of that buffer and do whatever they like. The off-screen buffer can be automatically merged into the parent window or merged by external programs, called compositing managers."^[1]

This enabled the creation of compositing managers for X, capable of effects like transparency, 3D rotation, and jiggly windows.

The composite extension was added to X.org in version X11R6.8^[2] in September 2004.^[3]
