Camera near Actor

[Lisa S. Avila]

Hello Satoshi,

Sorry, I though the ResetCameraClippingRange() method was in VTK 2.4. Yes,
you can reset the camera clipping range manually using
ren->GetActiveCamera()->SetClippingRange(near,far).  Use a small number
like 0.01 for near, and make far only as big as you need it to be (making
it too big will waste resolution in your depth buffer).
