In issue 1233 the behavior of Logmap was examined in detail, and a regression from GTSAM 4.0.3 to 4.2a7 was noted. In SO3.ipynb those graphs are reproduced so the issue can be further examined.

@ProfFan I'm at a loss right now how to simultaneously resolve #1233 and #887.

I thought about this for a while, and I think the best possible solutions are:
a) ignore the issue
b) figure out a smooth map between the two (interpolation)

Also could look into what Sophus is doing, need a bit of time for that
