commit 7ea01693a79964259e5f3b8678f412a0ac6ab066
Author: Jonas Ådahl <jadahl gmail com>
Date: Tue Jul 4 12:11:44 2017 +0800
backends/native: Move output code to its own file
Move code dealing with MetaOutputKms and related functionality to its
own file. Eventually, MetaOutputKms should become a GObject based on
MetaOutput, and this commit is in preparation for that.
