The old automatic clipping range code always grew
the bounds to be double the required bounds. With the
zbuffer being so heavily nonlinear this was not a good
for many situations. This topic alows you to control
the bounds expansion to it can be much tighter which
if you are calling ResetCameraClippiNgRange every time
the camera changes it should be set to 0.0 not the default
of 0.5.
