Instead of asking all backends to do that for us, we can call
ClutterStageWindow::redraw ourselves by default.
This changeset fixes all backends to actually do the right thing, and
move the stage implementation redraw inside the ClutterStageWindow
implementation itself.
This adds egl backend support for handling clipped redraws. This uses
the EGL_NOK_swap_region extension to enable the EGL backend to present a
subregion from the back buffer to the front so we don't always have to
redraw the entire stage for small updates.
Some minor fixes here and there: missing include, wrongly placed #endif,
unused variable warning fixes, missing #ifdef.
Make ClutterStageEGL a subclass of either ClutterStageX11 or GObject
depending if you compile with X11 support (EGLX) or not (native).
The glx and egl(x) backends export some internal symbols. Hide these
symbols (using '_' prefix) to reduce ABI differentiation between the
glx and eglx flavours.

Add initial EGL/X backend work mostly ported from backend branch.
Builds but untested as yet.
* clutter/glx/clutter-stage-glx.c:
Only include XFixes Header if we have have it.
* clutter/clutter-behaviour.c: (clutter_behaviour_apply):
* clutter/clutter-behaviour.h:
Add clutter_behaviour_is_applied()
* clutter/clutter-private.h: Remove inclusion of backend-specific
headers; update the main context object; add the declarations for
the event queue functions.
* clutter/clutter-backend.[ch]: Add the abstract ClutterBackend
object, which holds backend-specific settings, the main stage,
and the event queue. Every backend must implement a subclass of
ClutterBackend and ClutterStage.
* clutter/clutter-feature.c: Protect the GLX specific calls
behing #ifdef HAVE_CLUTTER_GLX.

* clutter/clutter-event.[ch]: Update public API and implement the
event queue private API; hold a reference on the event objects;
move out the keysym-to-unicode table; add the new event types.
* clutter/clutter-color.h: Include clutter-fixed.h
* clutter/clutter-main.c: Update API; get the main stage
from the backend object; process the event received from the
queue; lock/unlock the main mutex if we have one; move the
initialisation process sooner in the init sequence, in order to
have the backend object when we check for options; call the
backed vfuncs in the pre/post parse hooks.

implemented by the backends.
