near property
Distance to the near clipping plane. Geometry closer is clipped away.
Depth precision scales with the near plane, so a small one makes
distant surfaces a few centimeters apart flicker (z-fighting). A scene
rasterizes with the largest near plane that clips nothing visible, with
this as the floor (Scene.fitNearPlane), so leave it small enough that
nothing the camera approaches is clipped.
