Improve Blueprint Performance#5221

When using large scale blueprints (100k+ machines) the game becomes nearly unplayable even with a beefy computer on low settings. I believe this is because the entire blueprint is rendered at once and whatever performance optimizations there are for placed pieces isn’t applied.

Maybe just render dummy/unskinned/low poly/unanimated variants of pieces so I can continue building mega factories without having to copy them over in chunks.
