 Compositing managers such as xcompmgr and compiz allow X clients to render
 to an off-screen buffer and then have their contents composited onto the
 screen. This process allows arbitrary transformations of the window contents,
 such as translucency, magnification or changes in shape.
 .
 libcm provides support functions for compositing managers. This package
 provides the development headers for it.
