/**
 * Native bindings to the NV_depth_clamp extension.
 * 
 * In some rendering applications such as shadow volumes, it is useful
 * to allow line and polygon primitives to be rasterized without
 * clipping the primitive to the near or far clip volume planes (side
 * clip volume planes clip normally).  Without the near and far clip
 * planes, rasterization (pixel coverage determination) in X and Y
 * can proceed normally if we ignore the near and far clip planes.
 * The one major issue is that fragments of a  primitive may extend
 * beyond the conventional window space depth range for depth values
 * (typically the range [0,1]).  Rather than discarding fragments that
 * defy the window space depth range (effectively what near and far
 * plane clipping accomplish), the depth values can be clamped to the
 * current depth range.
 * 
 * This extension provides exactly such functionality.
