Circuit connections about factorio-railloader

[mspielberg]

The main reason for the proxy entities is that they have a different collision box that doesn't overlap the rails. On the other hand the actual (un)loaders have a 4x4 collision box to allow them to be attached to loaders or inserters on either side of the rails. You may be aware there's an ongoing discussion in the forum thread about changing this, such that loaders wouldn't be placed over existing rails, but would include the rail segments themselves. This has its own tradeoffs when deconstructing loaders, but makes for better behavior in blueprints.

I wasn't aware of that discussion, thanks for pointing that out. And I also didn't know about the rail collision issue, which adds a whole new layer of complexity to solving this. I'll think about this some more, and if I get to anything I'll come back to you.

This should be resolved in v0.3.7 now, by recording circuit connections from blueprints in a separate data structure whenever they are placed.
