DepthRange QML Type

By default, OpenGL writes scene depth information into the depth buffer in the range [0.0, 1.0] corresponding to the near and far clip planes. QDepthRange allows mapping these values into a different range. For example setting the range [0.0, 0.5] will map the rendered scene into the depth buffer such that objects at the near clip plane have depth value of 0.0 and objects at the far clip plane have a depth value of 0.5. This allows rendering parts of the scene always in front of or behind other parts.
