  A Viewport is a render node that sets the render viewport and depth range for
  its children.  It uses an array in the format [left, top, width, height] where
  left, top, width and height are in a 0.0 to 1.0 range that represent positions
  and dimensions relative to the size of the client's rendering area. The depth
  range is represented by an array in the format [min Z, max Z]. The depth range
  provides the mapping of the clip space coordinates into normalized z buffer
  coordinates.

    The position and size to set the viewport in
    [left, top, width, height] format. The default values
    are (0.0, 0.0, 1.0, 1.0). In other words, the full area.

    Note: These values must describe a rectangle that is 100% inside the client
    area. In other words, (0.5, 0.0, 1.0, 1.0) would describe an area that is
    1/2 off right side of the screen. That is an invalid value and will be
    clipped to (0.5, 0.0, 0.5, 1.0).
