[vtkusers] vtkOpenGLTexture GetIndex

[Ken Martin]

I'm guessing this is with the OpenGL1 backend. Looking at the code it looks
like it gets set when Load is called which in turn is called by Render. So
when the texture is rendered it will be set. Prior to then it looks like it
is initialized to zero.
