I don't believe this is really a bug in the implementation of extrude_along_path, but it is inconvenient and I would love a way around it. (Or pointers on what I'm doing wrong!)

When using extrude_along_path to make a simple rotation, for example to make a torus, the first and last faces in the path are at the "wrong" rotation. It seems like they just face the direction of the one neighboring point, which leaves a gap in a completed loop. I see this making sense if connect_ends=False, but when connect_ends=True, it seems better to treat the points as a loop rather than a path with geometry connecting the ends.

I modified the "No Scale" example from the examples file to have a lower num_points in the path, which highlights the issue.

connect_ends=False

connect_ends=True

If this behavior can't be changed due to backwards compatibility concerns, perhaps I could add a simple new function to replicate what rotate_extrude does in OpenSCAD? Having to manually define a circle_points function, then use it extrude, seems like extra work compared to how simple that built-in function is.

Alternatively, if there's something simple I've overlooked to fix this, I'd love to know!
