Merge lp:~unity-team/unity/unity.fix-810325-2 into lp:unity

[Mirco Müller]

The updated Unity-part of fixing LP: #810325. This makes sure the average color - computed after a change of wallpaper - is exposed via Unity's GSettings schema. That in turn can get picked up by other applications... notify-osd in this case.

[Gord Allott (gordallott)]

few things need fixing

24 + const gchar* AVG_BG_COLOR = "average-bg-color\0";
25 + const gchar* UNITY_SCHEMA = "com.canonical.Unity\0";

should use std::string not gchar*'s

35 + gchar* color_string = NULL;

should use unity::glib::String, from UnityCore/GlibWrapper.h - it will handle freeing when scope is lost for you and you can use it with methods.

41 + settings = g_settings_new (UNITY_SCHEMA);

we have a gsettings pointer in the object already, "client", should use that instead of creating another instance
