Subject: Refactor KeyFrame ownership management in Animation
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgl.git;a=commitdiff_plain;h=29ee3d841a610d24ccfa3e16e492e278f81f64bd

Refactor KeyFrame ownership management in Animation

The public add_keyframe functions no longer provide a convenient single
place to set the RefPtr keep flag, so move it into the private function.
