Subject: Temporary disable the sky reposition speedup code until I discover the magic key... 
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=80c8fbe4a30943bd41b716cbdd65753f39b501c8;p=flightgear.git

Temporary disable the sky reposition speedup code until I discover the magic key that unlocks the proper behaviour. It's not like this causes  a noticable decrease in framerate.
