Summary	0008659: vtkQuadricLODActor can cause SEGV if no properties set/changed
Description	When using vtkQuadricLODActor it will cause a segmentation fault if no properties are set on it. This is because its reimplementation of vtkActor::RenderOpaqueGeometry misses a test for a valid vtkProperty instance before calling vtkActor::GetIsOpaque whose first line is this: int result=this->Property->GetOpacity() >= 1.0; Property is NULL, so SEGV. I have attached the obvious trival fix to check for a valid vtkProperty instance and create one if necessary, as vtkActor does.
