Subject: Torsten Dreyer: the rotate animation has two ways to define a axis
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=812170ebce9c8e72de1191834d63d93a3698f204;p=simgear.git

Torsten Dreyer: 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.
