No functional changes.
Edges hidden by Optimal Display are hidden by edge factor Shader.
But there is not much advantage in doing this, as the number of edges
hidden by the Optimal Display is usually much higher than the number of
visible edges.
And the lines extractor does not include invisible edges due to other
factors.
So this change makes:
- Visibility test more consistent with what is actually seen.
- Smaller buffer for IBO sent to GPU
- consistency with GPU Subdivision that already considers Optimal Display
- Allows possible improvement in the "Edge Factor" extraction by making
it unnecessary to check the Optimal Display (except for optimization).
