[Paraview] Applying Texture with Plugin

[Brian C. Panneton (CONTR)]

I am able to set the color of the plane without an issue by using:

[code]
this->Actor->SetMapper(this->Mapper);
this->Property->SetColor(.8, .4, .2);
this->Actor->SetProperty(this->Property);
rview->GetRenderer()->AddActor(this->Actor);
rview->GetRenderer()->SetBackground(.1, .2, .3);
[/code]

So somehow, the texture is not loading properly. Does anyone know what 
is wrong here?

Thanks,
Brian
