0032400: Visualization, TKIVtk - convert VTK camera to OCC

Browse Source 
Add new interfaces GetEyePosition(), GetClippingRange(), GetAspectRatio() to IVTK_IView
Add ivtkviewparams command to print current parameters of view
Add ivtkcamera comand to print current camera parameters or manages camera parameters (set ortho or persp projection)
