Subject: Placement can contain multiple nodes.
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=49730cadeec1efaf6b2d51762d64f6aaa8947599;p=simgear.git

Placement can contain multiple nodes.

- Allow placement to have multiple children added.
- Remove legacy position setting APIs, enforce use of SGGeod
