Delete Branch "HooglyBoogly/blender:geometry-nodes-align-rotation-to-vector"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
A version of "Align Euler to Vector" with the rotation socket
instead of the vector Euler socket. Other than that, and a few
cleanups to use newer math functions, the node is the same.
The old node is just "Deprecated" for now. We could remove
it with versioning, but we can also wait to do that.
In a simple test this node is about 1.7 times faster than the old one.
Not sure, but I feel like it should be possible to achieve this without having to convert the quaternions to rotation matrices and back? That could also be left for a future update of course
Good point! That's worth looking into anyway, it might be simple.
Since we are now free from the arbitrary X/Y/Z axes when talking about rotations, would it make sense to change the pivot axis to a vector input socket?

I.e. either this should be
1, 0, 0or the default axis should be Z. Right now I'd argue for the latter, because people generally know better where the local Z axis is compared to the X or Y axis.
