Subject: Prevention of the creation of multiple OSG scene graph roots.
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=8ddfe51600d2f940c86116f25471ac27a44783a7;p=flightgear.git

Prevention of the creation of multiple OSG scene graph roots.

As the scenery manager's init() function is called twice on start up, two OSG
scene graph roots would be created.  A number of scene graph branches would be
initalised on the first root, but then be lost as the second is created.  This
fixes the precipitation branch, for example.
