+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.
