* change setBackground to updateBackground and move it to base class
* fix typo

relevant here.

Add support for the GLX_EXT_buffer_age extension on hardware that supports it, which should result in a nice speed-boost due to the fact that we no longer have to abuse fillrate by retaining old frame contents, and instead asking the driver how defined the current frame is.

Added external API for plugins to register their own damage tracking objects - with a callback as to whether or not to track the specified damage. This allows plugins that rely on both the retrospective and new damage to the framebuffer to ignore feedback caused by their old damage events.

(LP: #1024304)

Problem: Editors like gedit and others will not recognize *.xml.in files as xml, so if opened there is no syntax highlighting making those files harder to read.
This commit fixes this by adding <?xml version="1.0" encoding="UTF-8"?> to all *.xml.in files in lp:compiz 

Also fixed string copy operation in plugins/notification/src/notification.cpp by adding two + (it was working/not throwing any error with the #define of IMAGE_DIR, but does not work that way with a string)

the window should appear focused when switching between windows

Previously the switcher window was a normal managed window (which
the switcher plugin actually lied about, see SwitchWindow::managed),
such that the decorators could pick it up and draw the switcher
decoration. However now with reparenting, this means that whenever
we actually manage and unmanage the switcher window (eg with map
and unmap) it means we must also reparent the window, which floods
the server with requests and makes the switcher slow.

Since we don't interact with the switcher window, it makes no sense
to manage it like this, so make it override redirect

Don't require both opengl and composite since opengl already requires composite. This can cause flicker or momentary black screen with some drivers.

 * Rewrite PropertyWriter, move it out of compiztoolbox
 * Added CompPluginStateWriter, a serialization interface, which plugins inherit, and specify how to serialize their class members, which will be automatically unloaded and reloaded as plugins unload and reload.
 * Currently there are bugs with this interface, so it is disabled by default (mostly bugs to do with boost and libdl)
 * Depend on libboost-serialization
 * A few bugfixes

::resize and XMoveResizeWindow are mostly functions for internal use and they
don't correclty configure the window the way we need it. This results
in some weird display artefacts with the switcher popup window
