Hi,
the rotate animation has two ways to define a axis
1. by using center/x-m and axis/[xyz]
2. by using axis/[xyz]1-m and axis/[xyz]2-m
The translate animation only supports method 1. and here comes a patch that
enables method 2 for this animations, too.
Works fine for me and makes life a little easier.
I'd be happy if someone considers commiting this.
Thanks, Torsten
