-Subject: [PATCH 1/3] Add virtual output support
-
-Following patch ported to Weston 1.11 with minor updates
-----------
-Author: Grigory Kletsko <grigory.kletsko@cogentembedded.com>
-Date: Wed Nov 2 17:14:43 2016 +0300
-
-To enable virtual output set "virtual" property in core section
-to desirable number of virtual outputs. Then add settings to
-each virtual output in output sections. Name of the outputs
-will be virtual1, virtual2... etc.
