// DepthRange specifies the mapping of depth values from normalized device

// Parameter nearVal specifies the mapping of the near clipping plane to window
// coordinates (defaults to 0), while farVal specifies the mapping of the far
// clipping plane to window coordinates (defaults to 1).
//
// After clipping and division by w, depth coordinates range from -1 to 1,
// corresponding to the near and far clipping planes. DepthRange specifies a
// linear mapping of the normalized depth coordinates in this range to window
// depth coordinates. Regardless of the actual depth buffer implementation,
// window coordinate depth values are treated as though they range from 0 through 1
// (like color components). Thus, the values accepted by DepthRange are both
// clamped to this range before they are accepted.
//
// The default setting of (0, 1) maps the near plane to 0 and the far plane to 1.
// With this mapping, the depth buffer range is fully utilized.
//
// It is not necessary that nearVal be less than farVal. Reverse mappings such as
// nearVal 1, and farVal 0 are acceptable.
//
// GL.INVALID_OPERATION is generated if DepthRange is executed between the
