+The Composite extension causes a entire sub-tree of the window
+hierarchy to be rendered 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.

 %description devel
-(Upstream has not provided a description)
+The composite extension provides several related mechanisms:
+- Per-hierarchy storage: The rendering of an entire hierarchy of
+  windows is redirected to off-screen storage.
+- Automatic shadow update: When a hierarchy is rendered off-screen,
+  the X server provides an automatic mechanism for presenting those
+  contents within the parent window.
+- Composite overlay window: provides compositing managers with a
+  surface on which to draw without interference.
+- Parent window clipping: modifies the semantics of parent window
+  clipping in the presence of manual redirected children.
 
 This package contains the development headers for the library found
 in %lname.
