From 3a49e96f29a7cde711f376f2417875d54dd9f17f Mon Sep 17 00:00:00 2001 From: Giulio Camuffo Date: Wed, 29 Jan 2014 14:30:21 +0200 Subject: Add a libhybris hardwareintegrations to share EGL server buffers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a hardwareintegration plugin to make Qt server side EGL buffers shareable from the compositor to the client, such as what the server-buffer example does.
