< BLOCKQUOTE > ClearNode is a Group node which controls the clearing of the color and depth
buffers at the start of each frame.
The earth sky by default is empty and simply holds the clear color of
the background. However, if the uses wants to add their own clearing of
the color and depth buffers then the children can be added, and the
background clear turned off. The ClearNode by default has StateSet attached
to it which sets the default ClearNode bin number to -1, so that all drawables
below it are placed in a separate bin from the rest of the scene graph, and
are rendered prior to standard opaque and transparent drawables.< / BLOCKQUOTE >
